If line y bisects ac, ab = 4-5x, and bc =2x+25, find ac

38

Step-by-step explanation:

If line y bisects AC at B

Bisect means divide a line into two equal parts.

Therefore, AB=BC

where, AB = 4-5x and BC = 2x+25

4-5x = 2x+25

 -7x = 21

    x = -3

Thus,

AB = 4-5x

    = 4-5(-3)

    = 19

BC = 2x+25

     = 2(-3) + 25

     = 19

AC = AB+BC

     = 19 + 19

    = 38

Hence, The length of AC is 38

5x+10 is the correct one
