Answer:

26

Explanation:

AC = AB + BC

Since B is the midpoint

AB = BC

AC = AB + AB

Combine like terms

AC = 2 AB

8x-20 = 2(3x-1)

Distribute

8x-20 = 6x-2

Subtract 6x from each side

8x-6x -20 = 6x-6x -2

2x-20 = -2

Add 20 to each side

2x-20+20 = -2+20

2x= 18

2x/2 = 18/2

x =9

We want to find BC

We know BC = AB = 3x-1

BC = 3(9) -1

= 27-1

= 26
