12) 2b+8a
13) 17y^2-22y
14) 9m^2n+7mn^2
15) 11y^2
16) 8x^2y
The answer is 24. think of x as the original amount, and y as the new
amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y,
which is what we need, and you have x/1.5 = y as well as x-12 = y. Use
the equal values method and make an equation x/1.5=x-12. solve this
equation to get x, which is 36. to figure out the new amount, y, you
need to subtract 12, which would help you get 24 as your final answer.
4 * 45 = 180
265 - 180 = 85
85/5 = 17
