Question 1147161: R is between Q and S, S is between R and T. If QS=7, RT=6, and RS=2, find QT
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! QT is 11.
here's how it works out.
you are given that:
QS is 7 and RT is 6 and RS is 2.
since RS is 2, then QR is 5 and ST is 4.
going from left to right, you get:
QR is 5, RS is 2, ST is 4.
add them up and you get 11.
my diagram shows the breakdown.
Q----------------R---------------S--------------T
5 2 4
R---------------S
2
Q--------------------------------S
7
R--------------------------------T
6
QR is 7 - 2 = 5
ST is 6 - 2 = 4
