If T is the midpoint of SV, ST= x + 4, and TV= 2x - 8, how long is SV?

The answer to your question is SV = 32

Step-by-step explanation:

Data

T = mid point

ST = x + 4

TV = 2x - 8

SV = ?

Process

1.- If T is the mid point of SV, that means that the distance from ST to SV is the same.

                    ST = TV

2.- Substitution

               x + 4 = 2x - 8

-Solve for x

              x - 2x = -8 - 4

-Simplifying

                   -x = -12

-Result

                    x = 12

3.- Find the length of SV

                  SV = ST + TV

                  SV = x + 4 + 2x - 8

                  SV = 12 + 4 + 2(12) - 8

                  SV = 16 + 24 - 8

                  SV = 40 - 8

                  SV = 32
