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>
Answer:
C. 7h + 50 > 99
Step-by-step explanation:
She earns <u>more</u> than $99, so you know that the sign will be > (more than).
h is the number of hours, so to find how much she earns for working h hours at $7/hour, you multiply h by 7 --- 7h
She also earns an additional $50, which will be +50.
Therefore, the equation is: 7h + 50 > 99
Hope this helps :D
All you need to do it combine like terms.
3x + 9 + 4x + x
(3x + 4x + x) + 9
8x + 9
i hope this was helpful for you!
