Point b is between points a and c. if ab = 3x -1, bc=9x+8, and ac=139, find the measure of bc

BC = 107

Step-by-step explanation:

Point B is between A and C.

AB  = 3x-1

BC = 9x+8

AC = 139

We need to find BC for which we need to find x first.

Finding 'x':

We know that AB + BC = AC

*putting the values of AB, BC and AC*

3x-1+9x+8 = 139

12x+7=139

12x=132

x=132/12

x=11

Now, BC = 9x+8 = 9(11) +8

BC = 99+8

BC = 107

you answer is a

step-by-step explanation:

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
