Option C [tex]10+5x=24+3x[/tex]

Step-by-step explanation:

Let

x ------> the cost of each shirt

we know that

The cost of 5 shirts plus $10 (amount of money that would remain) must be equal to the cost of 3 shirts plus $24 (amount of money that would remain). Considering that the cost of the shirts is the same

The linear equation that represent this scenario is

[tex]10+5x=24+3x[/tex]

Solve for x

[tex]5x-3x=24-10[/tex]

[tex]2x=14[/tex]

[tex]x=\$7[/tex]

To determine the cost of each shirt, set up a system of equations with the given information. By solving the equations, we find that the cost of each shirt is represented by option C.

To determine the cost of each shirt, we can set up a system of equations based on the given information. Let x represent the cost of each shirt. We have the following equations:

We know that Rhonda had $10 left after buying five shirts, so equation A can be rewritten as 5x + 10 = 10. Simplifying this equation, we get 5x = 0, which means x = 0.

Now, let's substitute x = 0 into equation B. We get 3(0) + 24 = 24. Since Rhonda had $24 left after buying three shirts, this is the correct equation.

Therefore, the correct equation to determine the cost of each shirt is 3x + 24 = total amount spent. Option C represents this equation.

The answer is:

The second distance ([tex]distance_{2}[/tex]) is equal to 7.5 feet.

Since we are given two forces acting at distance, torque will be created. We are given two forces and one distance, so, to calculate the other distance required to balance the system (solve this fulcrum problem), we need to write the following equation:

[tex]Torque_{1}=Torque_{2}[/tex]

Where,

[tex]Torque=F*Distance[/tex]

We are given,

[tex]Force_{1}=Weight_{1}=150lb\\Force_{2}=Weight_{2}=30lb\\distance_{1}=15ft\\[/tex]

So, substituting and calculating, we have:

[tex]Torque_{1}=Torque_{2}[/tex]

[tex]Weight_{1}*distance_{1}=Weight_{2}*distance_{2}[/tex]

[tex]150lb*15ft=300lb*distance_{2}[/tex]

[tex]distance_{2}=\frac{150lb*15ft}{300lb}=7.5ft[/tex]

Hence, the second distance ([tex]distance_{2}[/tex]) is equal to 7.5 feet.

It's a logical solution since the second force is twice the first force and it means that the second distance must be equal to half the first distance in order to maintain the equilibrium condition.

Answer:

The length of the pen is [tex]8\ ft[/tex]

The width of the pen is [tex]6\ ft[/tex]

Step-by-step explanation:

Let

x-----> the length of the pen

y----> the width of the pen

we know that

The perimeter of the pen is

[tex]P=2(x+y)[/tex]

[tex]P=28\ ft[/tex]

so

[tex]28=2(x+y)[/tex]

[tex]14=(x+y)[/tex] ------> equation A

[tex]y=2+\frac{1}{2}x[/tex] -----> equation B

Substitute equation B in equation A and solve for x

[tex]14=x+(2+\frac{1}{2}x)[/tex]

[tex]14-2=\frac{3}{2}x)[/tex]

[tex]12=\frac{3}{2}x)[/tex]

[tex]x=12*2/3=8\ ft[/tex]

Find the value of y

[tex]y=2+\frac{1}{2}(8)=6\ ft[/tex]

therefore

The length of the pen is [tex]8\ ft[/tex]

The width of the pen is [tex]6\ ft[/tex]

John's dog pen is solved to have dimensions of 8 feet in length and 6 feet in width by using algebraic expressions to relate the given conditions about the pen's perimeter and the relationship between its length and width.

Let's solve John's problem by denoting the length of the rectangle as L and the width as W. According to the problem, we know that the entire fencing measures 28 feet, so the perimeter of the rectangle can be calculated as 2L + 2W = 28. Furthermore, it's given that the width is two more than one-half the length, which translates to W = ½L + 2.

First, substituting the width's equation into the perimeter equation gives us 2L + 2(½L + 2) = 28. Simplifying this equation leads to L = 8 feet. Plugging the length's value back into W = ½L + 2 gives W = 6 feet.

Therefore, John's dog pen has dimensions of 8 feet in length and 6 feet in width.

ANSWER

The value of x is 18.

EXPLANATION

The given expression is

[tex]2x + 3y = 36[/tex]

when y=6, we substitute y=6 into the expression to get:

[tex]2x + 3(6) = 36[/tex]

This gives us:

[tex]2x + 18= 36[/tex]

We group similar terms to obtain:

[tex]2x = 36 - 18[/tex]

We simplify the RHS to get

[tex]2x =18[/tex]

We divide both sides with 2 to get,

[tex]x = \frac{18}{2} [/tex]

x=9

Answer:

The value of x = 9

Step-by-step explanation:

It is given an expression in variables x and y

2x + 3y = 36

To find the value of x

Let 2x + 3y = 36

When y = 6, the expression becomes

2x + (3 * 6) = 36

2x + 18 = 36

2x = 36 - 18  = 18

2x = 18

x = 18/2 = 9

x = 9

Therefore the value of x = 9

Answer:

Length = 24 and Width = 81

Step-by-step explanation:

Let Width be W

then Length = W-57

Perimeter of rectangle = 2(Length + Width)

=2 (W-57+W)= 210

4W- 114= 210

4W= 324

W= 81

Then Length = 81-57 = 24

The length and width of a regulation singles tennis court is 78 feet and 27 feet respectively when the perimeter is 210 feet and length is 57 feet less than five times the width. This can be obtained by using formula of perimeter of a rectangle and algebraic expression.

P = 2(l + b) where P is the perimeter of the rectangle, l is the length of the rectangle and b is the width of the rectangle.

Length of the rectangle is 57 feet less than five times the width, that is, in the form of algebraic expression,

l = 5b - 57 , where l and b are length and width.

Given that, perimeter P=210 feet, length l= 5b - 57, width b = b

P = 2(l + b)

210 = 2((5b - 57) + b)

210 = 2(5b + b -57) =2(6b - 57)

210 = 12b - 114

12b = 210 + 114 = 324

b = 324/12 =27 ⇒b = 27 feet

l = 5b - 57

l = 5(27) - 57

l =135 - 57 =78 ⇒ l = 78 feet

l = 78 feet and b = 27 feet

Hence the length and width of a regulation singles tennis court is 78 feet and 27 feet respectively when the perimeter is 210 feet and length is 57 feet less than five times the width.

Plz mark Brainlist!!!

A pack of cards has 52 cards, 4 of which are kings, so the probability of the first card being a king is (4/52). Since you have already chosen a card, there are only 51 cards left to choose from in the entire deck (the first card is not counted anymore because it has already been pulled from the deck), and since the card you chose was a king, you are left with only 3 more kings, meaning that the probability of the second card being a king is (3/51). Since we are interested in both happening simultaneously, we must multiply the probability of the first by the probability of the second: (4/52) • (3/51), which leaves us with: * 12/2,652 or 0.0045249 *

To find the probability of holding 2 kings in a 2-card hand, you need to calculate the number of favorable outcomes and divide it by the total number of possible outcomes. In this case, there are 6 favorable outcomes out of 1,326 possible outcomes, resulting in a probability of approximately 0.0045 or 0.45%.

To find the probability of holding 2 kings in a 2-card hand, we first need to determine the total number of possible 2-card hands that can be dealt from a standard 52-card deck. The number of combinations of choosing 2 cards from 52 is given by the formula C(52, 2) = 52! / (2! * (52-2)!) = 1,326.

Next, we need to determine the number of favorable outcomes, which is the number of ways to choose 2 kings from the 4 kings in the deck. This can be calculated as C(4, 2) = 4! / (2! * (4-2)!) = 6.

Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes: P(2 kings) = 6/1,326 ≈ 0.0045 or 0.45%.

4.575% APEX

Step-by-step explanation:

The new rate would be 3.75% when Peter's bank offered him a 4.95% interest rate for his mortgage. If he purchases 3 points.

A mortgage exists as an arrangement between you and a lender that provides the lender the right to consider your property if you forget to repay the money you've borrowed plus interest.

Mortgage loans exists utilized to buy a home or to borrow money against the significance of a home you already possess.

Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of a 1% interest reduction.

A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)

New interest rate = 4.5% - 0.75% = 3.75%

[tex]\frac{(x+5)(x-3)}{(x+5)(x+1)}[/tex]

Step-by-step explanation:

A removeable discontinuity is always found in the denominator of a rational function and is one that can be reduced away with an identical term in the numerator.  It is still, however, a problem because it causes the denominator to equal 0 if filled in with the necessary value of x.  In my function above, the terms (x + 5) in the numerator and denominator can cancel each other out, leaving a hole in your graph at -5 since x doesn't exist at -5, but the x + 1 doesn't have anything to cancel out with, so this will present as a vertical asymptote in your graph at x = -1, a nonremoveable discontinuity.

Using the continuity concept, it is found that the function with both a removable and a non-removable discontinuity is:

[tex]f(x) = \frac{(x - 1)(x - 2)}{(x - 1)(x - 3)}[/tex]

----------------------------------------------

Continuity:

A function is not continuous at points that are outside it's domain.

An example can be taken considering a function as follows:

[tex]f(x) = \frac{(x - 1)(x - 2)}{(x - a)(x - b)}[/tex]

Final answer:

A 52% chance indicates that it is more likely than not for a player to win a carnival game, expecting roughly 52 wins out of 100 plays.

Explanation:

The likelihood that a player will win a certain carnival game, with a 52% chance, suggests that it is more likely than not that the player will win. This percentage can be interpreted as a probability of 0.52 (where 0 represents an impossible event and 1 represents a certainty). To describe this likelihood in terms of probability theory, if the game were played 100 times, we would expect the player to win approximately 52 times, although the actual outcome could vary due to randomness.

When comparing to other probabilities, such as a child winning one out of five times (20% chance) or the very low probability of winning the grand prize in another carnival game (0.005 or 0.5%), a 52% chance is relatively high, indicating that winning the game is a probable outcome.

The statement that describes the likelihood that a player will win the game is the fourth option

The likelihood of the player winning can be described as follows;

The probability that a player will win the carnival = 52%

The chance of a player winning the carnival is approximately 50%, which indicates that it almost equally likely or unlikely that a player may win the game

The above statement indicates that out of two plays, the player will likely win one and out of 10 palys, the player will likely win five

Therefore, the statement that describes the likelihood of a player will the game is the fourth statement

It is neither likely or unlikely that the player will win the game
