Solve this equation h + 17 = 40

Thanks!

Answers

Answer:

H= 40-17

H= 53

Therefore, h=23

Answer:

h=23

Step-by-step explanation:

Since h plus 17 is equal to 40, h needs to be a number that adds to 17 to get 40. Therefore, you can subtract 17 from 40 to get 23. If you add it into the equation you get 23+17=40 which is correct.

The length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if its area is 140 square centimeters?

Answers

Answer:

Dimensions = 7 cm by 20 cm.

Step-by-step explanation:

Let the length and width of the rectangle be L & W respectively.

Given the following data;

Area of rectangle = 140 cm²

L = W - 13

To find the dimensions of the rectangle;

The area of rectangle = L * W

Substituting into the above formula, we have;

140 = L * W

140 = (W - 13) * W

140 = W² - 13W

W² - 13W - 140 = 0

Solving the quadratic equation using factorization method;

Factors are -20 and 7

W² - 20W + 7W - 140 = 0

W(W - 20) + 7(W - 20) = 0

(W - 20)(W + 7) = 0

W - 20 = 0

W = 20

W + 7 = 0

W = -7

Thus, W = 20 or -7

But the width has to be positive, W = 20 centimeters.

Next, to find the length of rectangle

L = W - 13

L = 20 - 13

L = 7 centimeters.

What is the total interior measure of the polygon?

And what’s the value of x?

Answers

Answer:

x =196°

Step-by-step explanation:

The polygon is 5 sided, therefore, total interior angles of a pentagon is:

(n - 2) 180

(5 - 2) 180

(3) 180

540°

96° + 112° + 102° + 84° + x° = 540°

394° + x = 540°

Collect like terms

x = 540° - 394°

x = 196°

WILL GIVE BRAINLIEST FOR CORRECT ANSWER: All 5 students in Mrs.Awful's class score 50 on a test. What is the class's average score on this test?

Answers

Answer:

50

Step-by-step explanation:

If everyone scored 50, the average is just 50.

The math would also be:

50 + 50 + 50 + 50 + 50 / 5 = 250 / 5 = 50

Answer:

50

Step-by-step explanation:

In short explanation, since all the students scored the same score, the average will be the that score

Since all students scored 50, the average will be 50.

Proof:

[tex]50 + 50 + 50 + 50 + 50 = 250[/tex]

Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a+5b−3a+4b
Jada thinks 10a+1b is equivalent to the original expression.
Diego thinks 4a+9b is equivalent to the original expression.
Substitute your own values for “a” and “b” and determine if the expressions are equivalent. Show your work in the space provided.

Answers

Answer:

Diego's answer 4b+9b is correct:)

Step-by-step explanation:

Our first step is to combine like terms.

Causing you to combine 7a and -3a which gives you 4a because 7-3=4

Next, you would combine 5b and 4b which gives you 9b because 5+4=9

After you have combined like terms you would have your simplified equation 4b+9b causing Diego's answer to be correct!

Hope this helps!
