Answer:
2x+9
Step-by-step explanation:
(4x-15)-(2x-24)
4x - 2x - 15 - -24
4x - 2x - 15 + 24
2x - 15 + 24
2x + 9
2x+9
First set up proportion
18.75 : 27 = 100 : x
Then multiply outer numbers and inner numbers within each other.
18.75x = 2700
Then divide 2700 with 18.75 to get 144.
And 144 is the answer..
