Answer:

X=5

Step-by-step explanation:

The two bases added together divided by two should equal the mid segment which is 25. Plugging in the equation. You have (3x + 2) + (7x - 2) divided by 2. 7x + 3x = 10x. Then 2-2 cancel each other out. 10x/2 = 5x. 5x = 25. When you simplify it you get x = 5.

Answer:

Step-by-step explanation:

EF - base1

HG - base2

J-midpoint of EH

K-midpoint of FG

We are solving it by using formula:

JK=(base1+base2):2

25=(3x+2+7x-2):2

25*2=10x

50=10x

x=50:10

x=5

Good luck!

(8-16) + (8 + 6)
Furkat [3]

Step-by-step explanation:

Right now, we would solve everything within the parenthesis first.

(8 - 16) + (8 + 6)

(-8) + (14)

14 - 8

6

But if we remove the parenthesis, it doesn't matter what order we do things in.

8 - 16 + 8 + 6

8 + 8 - 16 + 6

16 - 16 + 6

6

The reason why both of these are the same, is because the only calculations we're doing are addition and subtraction, which don't care about parenthesis.

Answer:

A

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
11111nata11111 [884]

Answer:

She earned 1,076 dollars and 25 cents.

Step-by-step explanation:

x =  7.25 * 4,500 / 100

x = 7.25 * 45

x = 326.25

So commission earned is 326.25 $

We need to add this to her base salary for the week, so:

750 + 326.25 = 1, 076.25

Therefore she earned 1,076 dollars and 25 cents.

Hopes this helps ;p
