Question

Q bisects PR with a line over it. PQ=3y, and PR=42. find y and QR

Answer 1

To bisect a segment is to cut it in half. So, yes, Q is a point in the middle of segment PR.



Since point Q cuts the segment PR in half, that means that segment QR has the same length as segment PQ.

|----3y----|----3y---|
|-----------|-----------|
P........Q..........R
|----------42---------|

From the picture above, we get the equation:

3y + 3y = 42
6y = 42
y = 7
