Percent change = [(45 - 60) / 60] x 100 = -25 % (decrease)
Since AB and BC are two parts of AC, AC = AB + BC
let's plug the expressions from the question into our equation above.
19 = 3x + 1 + 2x - 7
Combine like terms
19 = 5x - 6
Add 6 to both sides.
25 = 5x
Divide both sides by 5
5 = x
The answer is A) b/(c+a)
Hope this helps
