Problem:

Matt and Tikka thought of the same number. Matt added 7 to that number and then doubled the result. He got 26. Tikka did the same operations with their number, but in reverse order. What did she get?

Please SHOW ALL YOUR WORK! (P.S. please show your work clearly, because I will need it for other problems! Thanks!)

Answers

Answer 1
First we need to find the number they started with.
(x+7)*2=26

Solve for x
x+7=13
x=6

To do the operations in reverse, we double it first and then add 7.
6*2=12
12+7=19

Final answer: 19
Answer 2
So first, you would take half of 26 since Matt doubled the result giving you 13. Then, subtract 7 which is 6.

For Tikka she did the opposite so take the 6, double it making 12, and then add 7 to get 19.

So the answer would be 19.

What is the missing term in the factorization?

12x^2-75=3(2x+?)(2x-5)

Can anybody help me asap please?
Thank you

Answers

3(2x+5)(2x-5), 5 is the missing term.

ANSWER

The missing term is

[tex]5[/tex]


EXPLANATION


The quadratic expression given to us is

[tex]12 {x}^{2} - 75[/tex]

We factor 3 to obtain,


[tex]12 {x}^{2} - 75 = 3(4 {x}^{2} - 25)[/tex]

We rewrite the expressions in the parenthesis to obtain,

[tex]12 {x}^{2} - 75 = 3( ({2x})^{2} - {5}^{2} )[/tex]



Recall that,


[tex] {a}^{2} - {b}^{2} = (a + b)(a - b)[/tex]



We apply the difference of two squares formula for the expression in the parenthesis to obtain,

[tex]12 {x}^{2} - 75 = 3(2x + 5)(2x - 5) )[/tex]



By comparing to,



[tex]12 {x}^{2} - 75 = 3(2x + ?)(2x - 5) )[/tex]

Using isosceles triangle theorems solve for x and y

Answers

Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5

Hope this helps! If you have anymore questions just ask!
Final answer:

To solve for x and y in a right triangle, use the Pythagorean Theorem (x² + y² = h²) and trigonometric relationships (x = hcosΘ and y = hsinΘ). The Isosceles Triangle Theorem, which states the base angles of an isosceles triangle are equal, isn't directly used to solve for x and y.

Explanation:

In solving for x and y using isosceles triangle theorems, we often utilize the Pythagorean Theorem and trigonometric relationships. Since this involves a right triangle, where x is the adjacent side, y is the opposite side, and h is the hypotenuse, we can use the formula for the Pythagorean Theorem, x² + y² = h².

To find x, we rearrange the trigonometric definition of cosine (cosΘ= x/h) to get x = hcosΘ. Similarly, we can find y using the definition of sine (sinΘ = y/h) and get y = hsinΘ. These solutions use trigonometry.

Keep in mind, the Isosceles Triangle Theorem states that the base angles of an isosceles triangle (a triangle with at least two equal sides) are equal. However, this theorem isn't directly involved in solving for x and y. Instead, the trigonometric relationships and Pythagorean Theorem solves for these values within a right triangle.

Write a real world situation that could be modeles by the equation 8+2x=6x.Then solve the problem

Answers

Final answer:

A real-world situation that could be modeled by the equation 8+2x=6x is a scenario where you have a certain amount of money and you are earning a fixed amount of money per hour. By solving the equation, you can determine how many hours it will take for your earned money to equal the given amount of money. To solve the problem, isolate the variable x by subtracting 2x from both sides and dividing both sides by 4.

Explanation:

A real-world situation that could be modeled by the equation 8+2x=6x is a scenario where you have a certain amount of money and you are earning a fixed amount of money per hour. Let's say you have $8 and you are earning $2 per hour. On the other side, you have $6 and you are earning $6 per hour. By solving the equation, you can determine how many hours it will take for your earned money to equal the given amount of money.

To solve the problem, you need to isolate the variable x. Start by subtracting 2x from both sides to get 8 = 4x. Then, divide both sides by 4 to get x = 2. Therefore, it will take 2 hours for your earned money to equal $6.

Final answer:

The bacteria in your culture appear to be experiencing exponential growth, doubling in population size every 20 minutes. This is common in organisms that reproduce by binary fission like bacteria, but the growth rate can be influenced by various environmental factors.

Explanation:

Based on your data, the number of bacteria in your culture seems to double every 20 minutes. This type of growth pattern is known as exponential growth, which is common in prokaryotes and other organisms that reproduce by binary fission.

For example, if you were to start with 1000 bacteria in a nutrient-rich environment, after one hour (or three 20-minute intervals), each bacterial cell would've divided several times, increasing the total population size from 1000 to 8000. This is based on the principle that in exponential growth, the number of new organisms added to the population in each round of division (or generation) increases as the population size increases. This results in a 'J-shaped' growth curve when plotted over time, illustrating the increasing rate of population growth.

However, please note that in reality, bacterial growth is influenced by several factors including nutrient availability and environmental conditions and the growth rate may not remain constant over time. For a more accurate analysis, you could take readings at more frequent intervals and plot a graph of population size versus time to observe the growth pattern.

angles x and y are supplementary.angle x is 3 times the measure of angle y what is the measure of angle x

Answers

Supplementary means that the angles add to 180. Thus, x + y = 180. But, we also have that x = 3y (stated in the question). Thus, we can substitute and say that 3y + y = 180 -> 4y = 180 -> y = 45. To find x, we substitute y into one of the two previous equations; I will use x = 3y. x = 3(45) -> x = 135.

In a 50-question test, the highest score in the class is three times the lowest score minus four. The difference between the highest score and the lowest score is 30. What is the highest score?

Answers

that's hard to answer to be honest with you.
Final answer:

The highest score on the test is 47, found by setting up and solving a system of equations based on the information given in the question.

Explanation:

The problem described in the question can be solved using algebra. Let's denote the highest score as H and the lowest score as L. According to the question, we have two equations:

H = 3L - 4 H - L = 30.

We can solve this system of equations step by step. Since both equations have H, they can be set equal to each other: 3L - 4 = 30 + L. If you simplify this equation by subtracting L from both sides, you get 2L - 4 = 30. Then add 4 to both sides to isolate 2L on one side: 2L = 34. Divide both sides by 2, to solve for L: L = 17. Then substitute L into one of your original equations (H = 3L - 4), so H = 3*17 - 4 = 51 - 4 = 47. So, the highest test score is 47.

Answer:

The king left his castle with 44 silver coins.

Step-by-step explanation:

A king left his castle with a bag of silver coins and he gave his coins to 3 peasants in an order. Finally he went home with two coins left.

To solve this question we calculate it in reverse order.

Finally the king has in his bag = 2 coins

Before it he met third peasant king had =

= (2+2) × 2

= 4×2 = 8

Before the king met third peasant, he had 8 coins.

Before he met Second peasant king had :

= (8+2) × 2

= 10 × 2 = 20

Before he met second peasant king had 20 coins.

Before he met first peasant he had :

= (20+ 2) × 2

= 22 × 2 = 44

Before King met first peasant he had 44 silver coins.

Well you need to find the value of x. So this is what you do. You have to isolate the variable in other words it needs to be on one side of the equation. You would need to add 11 to both sides and you would get 13x= 9x -2. Then you do the same with 9x and subtract it from boths sides and end up with 4x= -2. You divide -2 by 4 and get -1/2 as your answer. So x= -1/2. I hope this helps love! :)

The useful hint here is the shape of the area which is square. By definition, a square is a two-dimensional figure that consist of two parallel sides have the same equal measure. The only given dimension of a square is its side. The area is equal to the square of the side. Since the side has a measure of x²y³,

A = s² = (x²y³)²
By the laws of exponents, for this problem, just simply distribute the outer exponent to each of the inner exponent.

The high school marching band rehearses with either 6 or 10 members in every line.What is the smallest number of people who can be in the marching band?

Answer:

The smallest number of people who can be in the marching band are 30.

Step-by-step explanation:

The high school marching band rehearses with either 6 or 10 members in every line.

To get the smallest number of people who can be in the marching band, we will find the LCM of 6 and 10.

6 = 2 x 3

10 = 2 x 5

The LCM is 2 x 3 x 5 = 30.

Hence, the smallest number of people who can be in the marching band are 30.

If the students are 6 in each line, then there will be 5 lines in total.

If the students are 10 in each line, there will be 3 lines in total.
