Answer:
12x+3x+1 = 15x+1
8r+2+2+-3 = 8r+1
8p+7-p+1 = 7p+8
4xy+17+14xy-xy = 17xy+17
11+4-2b+8b = 15+6b
Step-by-step explanation:
Did the best I could.
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
The answer is 8%. Take the difference of the numbers, put that as the numerator and put the first number in the denominator. Then convert to a percentage. Viola!
