B is the midpoint of ac. if ab=8x-7 bc=6x+7 find ac
quester [9]

Answer: AC = 98

Step-by-step explanation:

A midpoint is a point on a line segment that divides it into <em>two equal parts</em>.

This means AB = BC

AB = 8x - 7

BC = 6x + 7

AB = BC

8x - 7 = 6x + 7

Solve this to find x

Add 7 to both sides

8x = 6x + 14

Subtract 6x from both sides

2x = 14

Divide both sides by 2

x = 7

Now AC = AB + BC

AC = AB + BC

AC = 8x - 7 + 6x + 7

AC = 14x

Substitute 7 for x

AC = 14(7)

AC = 98

Hope this helps!
