Question

B FB is the midpoint of Ac, and
AC=8x-20 find BC
3x-1

Answer 1

AC=52

BC=26

Explanation:

We are given a line Line Segment AC and B is the midpoint of AC.

Given that BC=3x-1 and AC=8x-20

Hence AC = 2 x BC

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

8x-20=6x-2

8x-6x=20-2

2x=18

x=9

Hence

AC= 8x-20

= 8(9)-20

= 72-20

= 52

Also

2BC= AC

BC=26
