B is miles he went, for c at the rate he's going at he'll probably be there after five minutes that is all I know
Step-by-step explanation:
3x x 10 = 22
3x x 10 - 10 = 22 - 10
3x = 12
3x ÷ 3 = 12 ÷ 3
x = 4
5x + 8
5(4) + 8
20 + 8
28
For this problem, just multiply the fractions by the amount of packages purchased.
6 * 1/4 = 1 1/2
8 * 1/2 = 4
7 * 3/4 = 5 1/4
