Answer:
31.5 $
Step-by-step explanation:
First lets se how much 1 pound of pasta costs in the store. We do this dividing the price for 8 pounds over those 8 pounds:
12/8 = $1.5 each pound
As 21 pounds are needed:
$1.5 * 21 = $31.5
Answer:
6x+24
Step-by-step explanation:
6(3x+3) = 18x+18
-3(4x-2) = -12x+6
(18x+18) + (-12x+6) = 6x+24
5/8 as a decimal would be 5/8 times 100/x because if you found the equivilent fraction you would be able to multiply it by the upside-down-fraction and get 1 for example 2/4 =1/2 if you multiply 4/2 with 1/2 you would get 4/4 or 1
so 5/8 times 100/x =500/8x=1
then use long division to solve 62.5/100=62.5%
