Point b is between points a and C. AB=2x+5 and BC=5x-1. What is the length of AB

1 answer:

7 0

Answer: AB = 9

Step-by-step explanation:

Since B is the midpoint, AB and BC must be congruent (since theyre both half of the segment). The equation is:

2x + 5 = 5x - 1

This means x = 2, meaning AB is 9.
