Question

Find the value riven by the problem

Answer 1

SM = 13

Explanation:

M is the midpoint of ST, then

SM = MT , that is

2x + 3 = 4x - 7 ( subtract 4x from both sides )

- 2x + 3 = - 7 ( subtract 3 from both sides )

- 2x = - 10 ( divide both sides by - 2 )

x = 5

Then

SM = 2x + 3 = 2(5) + 3 = 10 + 3 = 13
