Question

Measure Length

Answer 1

point Q is the midpoint so GQ = (1/2)GH

therefore

2x + 3 = (1/2)(5x-5)

the first step, solve for x, then plug x back into GQ = 2x + 3

Answer 2

2x + 8 = 1/2(5x)

Answer 3

2x + 8 = 2.5x

Answer 4

be careful with your order of operations

2x + 3 = (1/2)(5x-5)


you can't add 5 to both sides yet b/c you still have that (1/2) to deal with. multiplication comes before subtraction.

so my advice would be to multiply both sides by 2 first to get rid of the fraction

4x + 6 = 5x - 5

and proceed from there

Answer 5

4x + 6 = 5x - 5
4x + 11 = 5x

Answer 6

-1x +11
x= -11

Answer 7

careful with your signs

4x + 11 = 5x
subtract 4x from both sides

11 = x
so x = 11 not -11

next step, plug x = 11 into 2x + 3

Answer 8

25

Answer 9

11 x 2 + 3 = 25

Answer 10

GQ = 25 units

Answer 11

36?

Answer 12
