Use the number line​ below, where ​RS = 9y+2, ST = 4y+9 and RT = 115. a. What is the value of​ y? b. Find RS and ST. a. What is the value of​ y?

Answer 1

I am assuming point S is between points R and T.

Therefore RS + ST = total length

Equation is:

9 y + 2 + 4 y +9 = 115 now solve for y

then substitute in for

answers should be:

y = 8, 9 y + 2 =74, 4 y + 9 = 41
