Answer:
$2.73 per gallon.
Step-by-step explanation:
Divide 18 from 49.10 to find the unit rate.
49.10/ 18 = 2.7277... <em>The seven is continued.</em>
2.7277... is the unit rate.
The cost per gallon is $2.73
Answer:
x=-2
y=-3
Step-by-step explanation:
-9x+4y = 6
9x+5y = -33
We will add these together to eliminate x
-9x+4y = 6
9x+5y = -33
----------------
0x +9y =- 27
9y = -27
Divide by 9
9y/9 = -27/9
y =-3
We still need to find x
9x +5y = -33
9x +5(-3) = -33
9x-15 = -33
Add 15 from each side
9x+15-15 =-33+15
9x=-18
Divide by 9
9x/9 = -18/9
x = -2
V = 4/3 * (pi) * r^3
V = 4/3 * (pi) * 10^3
V = 4/3 * (pi) * 1000
V = 4000/3(pi)
V = 1333 1/3 (pi) in^3 <==
