a.
Let x = # of hours
Let y = cost to rent skates
3 + 2x = y
b.
(Plug in 8 for x, because it is the # of hours)
3 + 2x = y
3 + 2(8) = y
(PEMDAS or order of operations)
3 + 16 = y
19 = y
It costs $19 to rent skates for 8 hours.
Answer:
40
Step-by-step explanation:
12 is 30% of 40
30% x X = 12 or 30/100 x = 12
so if you multiply both sides by 100 and divide both sides by 30
we get X = 12 x 100/30
= 40
(BTW if you want to use a calculator just put 12×100÷30 which will give you the answer)
