Question

5. Point U is the midpoint of ty. Find the value of x. Round to the nearest tenth if necessary.

Answer 1

The value of x is 8.5.

Solution:

U is the mid-point of TV.

TU = 6

UV = 2x - 11

TU = UV

6 = 2x - 11

Add 11 on both sides.

6 + 11 = 2x - 11 + 11

17 = 2x

Divide by 2 on both sides.

$\frac{17}{2} =\frac{2x}{2}$

8.5 = x

Switch the sides.

x = 8.5

Option B is the correct answer.
