We need to convert the mileage from mi/gal units into to km/L units using the conversion factors.
(31.0 mi/gal) x (1 km / 0.6214 mi) x (1 gal / 3.78 L) = 13.20 km/L
Next, we divide the distance by the mileage.
(142 km) / (13.20 km/L) = 10.79 L
<span>Therefore, you need 10.79 liters of gasoline.</span>
Volume = Length x width x height
Volume = 5 1/2 x 3 x 3 = 49.5 cubic feet
Say x is the number
7x +3 = 39 -2x
Add 2x to each side
9x +3 =39
Subtract 3 from each side
9x =36
Divide by 9 on each side
x=4
Hope this helped
Answer:
Im gonna go with A
Step-by-step explanation:
36 / x = 12 / 10
12x = 360
x = 30
The correct answer is C. 30 inches.
Hope this helps! :)
