If Y is the midpoint of R and T. and RY = 3x - 2 and YT = 8x - 22. Find the value of RT. *
Your answer

11x-24

Step-by-step explanation:

All you have to do is add (3x-2)+(8x-22)=11x-24.

RT = 20

Step-by-step explanation:

Since Y is the midpoint of RT , then

RY = YT , that is

3x - 2 = 8x - 22 ( subtract 8x from both sides )

- 5x - 2 = - 22 ( add 2 to both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

Then

RT = RY + YT = 3x - 2 + 8x - 22 = 11x - 24 , so

RT = 11(4) - 24 = 44 - 24 = 20
