you cannot multiply any of the numbers above by another to get 12, the factors of 12 would be 1,2,3,4,6,12 1x12= 12 2x6=12 4x3=12
[-½, ¾]; use either "Substitution" or "Elimination" to do this, and you'll see that this answer is correct.
20 is the answer.
15% of 50= 7.5
45% of 50= 22.5
22.5+7.5=30
50-30=20.
25.25 bc 76 divided by 5 because the answer will not go evenly so you have to have a decimal
