If RV=w and SU=w–30, what is the value of w?

gtnhenbr [62]

Answer:

w = 60

Step-by-step explanation:

the midsegment SU is half the measure of side RV , then

SU = $\frac{1}{2}$ RV , so

w - 30 = $\frac{1}{2}$ w ( multiply through by 2 to clear the fraction )

2w - 60 = w ( subtract w from both sides )

w - 60 = 0 ( add 60 to both sides )

w = 60
