Answer:   27

======================================================

Explanation:

Since T is the midpoint of PQ, this means the smaller pieces PT and TQ must be equal. In other words, T divides PQ in half.

PT = TQ

5x+7 = 9x-9

5x-9x = -9-7

-4x = -16

x = -16/(-4)

x = 4

Use this to find each segment length.

  • PT = 5x+7 = 5(4)+7 = 20+7 = 27
  • TQ = 9x-9 = 9(4)-9 = 36-9 = 27

Both pieces are 27 units long, which confirms the answer.
