Question

Q is between P and S. R is between Q and S. S is between Q and T. PT=30, QS=16, and PQ=QR=RS. Find PQ.
8
6
16
12

Answer 1

8. If you draw them on a line from P to T. Then call PQ x, and ST y. Then you get two eqns x+y=14 and 3x+y=30. Solve simult to get x=8. Or equiv. you know that QS=16 and both parts are equal to PQ so 2x=16.

Answer 2

We know that the distance between Q and S = 16. But we know that QS = QR +RS. And we know taht PQ = QR=Rs. Substiture in we get QS = 16 = 2PQ. hence PQ=16/2 = 8.

Answer 3

so its 8??

Answer 4

Yes

Answer 5

yep
