If A is the midpoint of line segment PR, PA = 7x - 11, and PR = 8x +14, then what is the value of line segment AR?

Given that:

A is the midpoint of line segment PR.

PA = 7x - 11 and PR = 8x +14.

Solution:

Since A is the midpoint of line segment PR.

Using segment addition property, we get

Isolate variable terms.

Divide both sides by 6.

The value of x is 6.

Now,

Therefore, the value of line segment AR is 31 units.
