Answer:
13.2 gallons
Step-by-step explanation:
286/260 *12 = 13.2
about 13.2 gallons
Easy way to calculate.
12 gallons divided by 260 miles
Take that answer and multiply it by 286.
32/3 cubic
D.32/3
32/3=32:2= D.8 units
-3 (2a-9b+5c)
common factor out the lowest common factor which is -3
2x-10=8
2x = 10 + 8
2x = 18
x = 18 : 2 =
x = 9
-----------------------
check
2 * 9 - 10 = 8 (remember PEMDAS)
18 - 10 = 8
8 = 8
the answer is good
