Answer:

Q is not the midpoint of PR

Explanation:

see the attached figure to better understand the problem

we know that

If Q is the midpoint of PR

then

PQ=QR

substitute the given values and solve for x


15x-2=5x+3\\15x-5x=3+2\\10x=5\\x=0.5

Remember that


PR=5\ ft ----> given problem


PR=PQ+QR\\PR=(15x-2)+(5x+3)

substitute the value of x


PR=(15(0.5)-2)+(5(0.5)+3)


PR=(5.5)+(5.5)


PR=11\ ft

Compare with the given value of PR


5\ ft\\eq 11\ ft

therefore

Q is not the midpoint of PR
