Point s is between r and t on line segment rt. use the given information to write an equation in terms of x.
solve the equation. then find rs and st.
a. rs = 2x-10. st = x-4. and rt = 21
b. rs = 3x-16. st = 4x-8. and rt= 60
c. rs= 2x-8. st = 3x-10. and rt = 17

                b)   x = 12         RS = 20            ST = 40

                c)    x = 7          RS = 6               ST = 11

Step-by-step explanation:

Use the Segment Addition Postulate: RS + ST = RT

a) (2x - 10) + (x - 4) = 21

                   3x - 14 = 21

                   3x       = 35

                    x        

RS = 2x - 10

ST = RT - RS

Use the same formula to solve for b and c
