12.375 = (1 x 10) + (2 x 1) + (3/10) + (7/100) + (5/1000). Hope this helps..
4(4x)+2(x)=72
16x+2x=72
18x=72
x=4
Answer:
She will need 7 tanks of gas. It will cost $273.
Step-by-step explanation:
First, we divide the amount of miles that she needs to go by the amount she can drive on one tank.
2240/320 = 7
She will need 7 tanks. Multiply the cost of one tank by 7.
$39*7 = $273
It will cost $273 total.
42 gallons weigh 7(42) or 294 pounds
<span>each cubic foot weighs 52 pounds </span>
<span>so the number of cubic feet = 294/52 = 5.654 ft^3</span>
