Answer: 19.5 gallons
Step-by-step explanation:
Hi, to answer this question, we have to use proportions:
Nathaniel buys 28 gallons of gas for $56, so the proportion is:
$56 / 28 gallons.
For $39:
$39 / x gallons
Solving for x (number of gallons)
56/28 = 39/x
x = 39 / (56/28)
x = 19.5 gallons

17-6 x 10/2+ 12
17-60/2+12
17-30+12
17-18
= -1
