Answer:
"Process is shown below"
Step-by-step explanation:
Since collinear, they are on the same line. They are positioned as below:
B-----------------------A-------------------C
AB, BC, and AC's expressions are given.
To find BC, first looking at the picture, we can say:
BC = AB + AC
Putting the expressions and solving for x:
7x+5 = 4x - 3 + 5x - 16
7x + 5 = 9x - 19
19 + 5 = 9x - 7x
24 = 2x
x = 12
1. BC = 7x + 5 = 7(12) + 5 = 89
2. AB = 4x - 3 = 4(12) - 3 = 48 - 3 = 45
3. AC = 5x - 16 = 5(12) - 16 = 60 - 16 = 44
