Answer:

see below

Step-by-step explanation:

Using the segment addition postulate

AB + BC = AC

x+2 + 7x-3 = AC

Combine like terms

8x -1 = AC

Using the segment addition postulate

PQ + QR = PR

8y+5 + QR = 13y+25

Subtract 8y from each side

5 + QR = 13y-8y+25

5 + QR = 5y+25

Subtract 5 from each side

QR = 5y+25-5

QR = 5y+20
