Answer:

b=16

Step-by-step explanation:

Formula~ 1/2*b*h

1/2*15*b=120

7.5b=120

b=120/7.5

b=16

(you can substitute the value to check-i've done it below)

1/2*16*15=?

if you work it out, the ans will be 120, therefore the ans is correct!

Answer:

First one: x = 3, and y = 2

Second: 5

Third: Yes because he will have $37.50

Fourth: The numbers 2.5 and 3 will make it true

Step-by-step explanation:

1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19

2. 4x + 2 = 22, 4x = 20, x = 5

3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5

He will get $37.50, which is enough.

4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.

Answer:

The value of x is 49 and the value of AB is 90

Step-by-step explanation:

You know that AB and DE are congruent. That information is given to you.

You set the equations equal to each other and then solve.


2x - 8 = x + 38


Subtract x


x - 8 = 38


Add 8.


x = 49


Plug back into 2x - 8 to find the value of AB


2 times 49 - 8


98 - 8


90
