The four consecutive even integers are 20, 22, 24, 26
Solution:
Let the four consecutive even integers are a , a + 2, a + 4, a + 6
Let "a" be the smallest integer and "a + 6" be the largest integer
To find: the four consecutive even integers
Given that the greatest of four consecutive even integers is 14 less than twice the smallest integer
largest integer = twice the smallest integer - 14
a + 6 = 2(a) - 14
a + 6 = 2a - 14
a - 2a = -14 - 6
-a = -20
a = 20
Thus the four consecutive even integers are:
a = 20
a + 2 = 20 + 2 = 22
a + 4 = 20 + 4 = 24
a + 6 = 20 + 6 = 26
Thus the four consecutive even integers are 20, 22, 24, 26
What is 5/2 - blank = 1/3
Step-by-step explanation:
taking that blank as x
5/2 -x = 1/3
the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3
so the equation will become 5/2-1/3=x
solving the fraction then gives 13/6 or 2.17 as the value of x
The value of the equation is x = 13 / 6
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

y-x=15 y-x=5 using elimination
Answer:
No solution
Step-by-step explanation:
To eliminate is to get rid of one of the variables.
You can choose to either add each term in the equations or subtract each term in the equation.
For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.
Try adding them.
. y - x = 15
+ y - x = 5
2y - 2x = 20 No variables were eliminated.
Try subtracting.
. y - x = 15
- y - x = 5
0y - 0x = 10 All variables were eliminated.
. 0 = 10 This is false.
This system of equations cannot be solved.
Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.
Find the measure of (Full question above)
Answer:
∠RUS = 90°
Step-by-step explanation:
PT is a line. This means that it has a measure of 180°
This means that all of the angles that it is broken up into must add together to equal 180°.
In this case, ∠PUQ +∠QUR +∠RUS +∠SUT = 180°
As we have the measures for all of the angles aside from ∠RUS, we can solve for that
First, let us input each of the measures of the angles
39+23+∠RUS+28=180
Now all we need to do is isolate ∠RUS by subtracting everything to the other side
Once that is done, we get
∠RUS = 90°
Answer:

the most expensive car he can afford?
O
A. $25,196.78
B. $22,241.32
O
c. $25,167.83
O D. $24,880.83
Answer: $22,241.32 APEX
Final answer:
By calculating the present value of an annuity using the monthly payment, interest rate, and number of payments, we find that Bryce can afford a car with a value of approximately $22,241.32.
Explanation:
To calculate the value of the most expensive car Bryce can afford based on a $350-per-month car payment with a 6-year loan at an APR of 4.2%, compounded monthly, we use the formula for the present value of an annuity:
PV = PMT × ¶ [(1 - (1 + r)^-nt) / r]
Where:
PV = Present Value (what we're solving for, the cost of the car)
PMT = Monthly Payment ($350)
r = monthly interest rate (APR divided by 12)
n = number of times the payment is made per year (12)
t = number of years (6)
Given:
APR = 4.2% per year or 0.042
Monthly interest rate, r = 0.042 / 12 = 0.0035
nt = 12 × 6 = 72 payments in total
Now we substitute the given values into the formula:
PV = $350 × [(1 - (1 + 0.0035)^-72) / 0.0035]
PV = $350 × [(1 - (1 + 0.0035)^-72) / 0.0035]
PV ≈ $350 × [(1 - (1.0035)^-72) / 0.0035]
Using a calculator to find (1.0035)^-72 and then the whole expression, we get:
PV ≈ $350 × 60.4774
PV ≈ $21,167.09
The value that's closest to our calculation and offered in the options is $22,241.32, so the most expensive car Bryce can afford is approximately $22,241.32.

But, I am assuming one of the answer choices may have included some negative number under a square root, as a real number cannot have a negative number under a square root. So, whatever the choice may have contained the negative number under a square root would represent the complex number. Anyhow, I would try to clear your concept.
So, lets move forward.
A complex number is basically the combination of a real number and imaginary number which can be expressed in the form of [tex]a+ib[/tex]. where a and b are termed as real numbers and i is a solution of the equation x² = -1.
So,
In [tex]a+ib[/tex],
"i" is called iota.[tex]i=\sqrt{-1}[/tex]For example, let us consider
[tex]2 + \sqrt{-1}[/tex]
Here, 2 is a real part, And [tex]\sqrt{-1}[/tex] is imaginary part, meaning [tex]i=\sqrt{-1}[/tex], which is imaginary part.Therefore, [tex]2 + \sqrt{-1}[/tex] is a complex number.

Hope this helps!!!
Karen rides farther.
What is comparison?Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given that, Harry rides his bike 25 3/8 miles. Karen rides her bike 25 2/5 miles, we are asked to find who rides farther,
Harry's distance = 25 3/8 = 203/8
Karen's distance = 25 2/5 = 127/5
Subtracting Harry's distance by Karen's distance,
203/8 - 127/5
= 1015-1016/40
= -1/40
Since, the result is in minus that means 127/5 is greater than 203/8.
Therefore, Karen's covers more distance than Harry.

Pizza Land delivered 144 pizzas in 8 hours on Saturday at that rate, how many pizzas can they deliver in 3 hours
Answer:
54
Step-by-step explanation:
144 divided by 8 is 18
so that means that their hourly rate 18 pizzas per hour
so multiply 18 by 3 and get 54
Given that Pizza Land can deliver 18 pizzas per hour, they can deliver 54 pizzas in three hours.
Explanation:The question is asking us to figure out how many pizzas can be delivered in 3 hours, if Pizza Land can deliver 144 pizzas in 8 hours. This is a rate problem. To solve it, we first need to find out how many pizzas are delivered per hour. We do this by dividing 144 (the total number of pizzas delivered) by 8 (the total number of hours). This gives us 18 pizzas per hour.
Now that we know how many pizzas are delivered per hour, we can multiply this by 3 (the number of hours we are interested in) to get the total number of pizzas that can be delivered in 3 hours. So, 18 pizzas/hour x 3 hours gives us 54 pizzas that can be delivered in 3 hours.

Mike invested a total of $25,000, some money in stocks and some money in bonds. The stocks earned 7% simple interest while the bonds earned 11% simple interest. Mike earned $2010 interest on his investments. How much money did he invest in bonds?
He invested $6500 in bonds
Step-by-step explanation:
The formula of the simple interest is I = Prt, where
P is the invested amountr is the rate of interest in decimalt is the time of investmentAssume that Mike invested $x in stocks and $y in bonds
∵ Mike invested $x in stocks
∵ Mike invested $y in bonds
∵ Mike invested a total of $25,000
∴ x + y = 25000 ⇒ (1)
∵ The interest rate of the stocks is 7%
∴ r of the stocks = 7 ÷ 100 = 0.07
∴ I (stocks) = x(0.07)(1)
∴ I (stocks) = 0.07x
∵ The interest rate of the bonds is 11%
∴ r of the bonds = 11 ÷ 100 = 0.11
∴ I (bonds) = y(0.11)(1)
∴ I (bonds) = 0.11y
∵ Mike earned $2010 interest on his investments
- Equate the sum of I (stocks) and I (bonds) by 2010
∴ 0.07x + 0.11y = 2010 ⇒ (2)
Now we have a system of equations to solve it
Multiply equation (1) by -0.11 to eliminate y
∵ -0.11x - 0.11y = -2750 ⇒ (3)
- Add equations (2) and (3)
∴ -0.04x = -740
- Divide both sides by -0.04
∴ x = 18500
- Substitute the value of x in equation (1) to find y
∵ 18500 + y = 25000
- Subtract 18500 from both sides
∴ y = 6500
∵ y represents the amount of money he invested in bonds
∴ He invested $6500 in bonds
He invested $6500 in bonds

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The correlation coefficient helps us to know how strong is the relation between two variables.
The value is always between +1 to -1, where, the numerical value shows how strong the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
1 indicates a strong positive relationship.
-1 indicates a strong negative relationship.
A result of zero indicates no relationship at all, therefore, an independent variable.
Since the scatterplot is the relationship between the two variables and as in the first graph the value of a single x can return multiple values for y.
Therefore, the scatterplot that has a stronger correlation is B.
