Question

Can someone help me solve this problem?

Answer 1

No

Explanation:

If Q is the midpoint of PR, then PQ=QR.

`5(x+2)=8x-3 \\ \\ 5x+10=8x-3 \\ \\ 3x=13 \\ \\ x=(13)/(3) \\ \\ \implies PQ=5\left((8)/(3) +2 \right) \\eq 36`

This means PQ + QR = PR isn't 72, and thus Q is not the midpoint of PR.
