Help.. Suppose Q is the midpoint of PR

Mathematics
1 answer:
8090 [49]3 years ago
6 0

Answer:

3x+41 or 38

Step-by-step explanation:

If Q is the midpoint of Line PR, then lines PQ and QR add up to equal Line PR. We then get

PQ=6x+25\\QR=16-3x\\PQ+QR=PR\\6x+25+16-3x=PR\\3x+41=PR\\

If you want to know the exact number that PR is, we can do additional steps where PQ = QR.

PQ=6x+25\\QR=16-3x\\PQ=QR\\6x+25=16-3x\\9x+25=16\\9x=-9\\x=-1\\\\3x+41=PR\\3(-1)+41=PR\\-3+41=PR\\38=PR\\PR=38
