What is the miles-per-gallon rating of this car?
How many miles for 1 gallon?
4.8 gallons are used for 100 miles. So
4.8 gallons - 100 miles
1 gallon - x miles
![4.8x = 100](https://tex.z-dn.net/?f=4.8x%20%3D%20100)
![x = \frac{100}{4.8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B100%7D%7B4.8%7D)
![x = 20.83](https://tex.z-dn.net/?f=x%20%3D%2020.83)
The miles-per-gallon rating of this car is 20.83.

Answer:
9 cats
Step-by-step explanation:
x = cat
y = dog
Set up equations.
x + y = 30
4.5x + 8.5y = 219
Multiply first equation by 4.5 and subtract.
4.5x + 4.5y = 135
-(4.5x + 8.5y = 219)
-4y = -84
y = 21
Substitute this y value into the first equation
x + y = 30
x + 21 = 30
x = 9
The value of 7 in 870,541 is 10,000
Answer:
15, 18, 21
Step-by-step explanation:
3, 6, 9, 12, 15, 18, 21...
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
Hope this helps! :)
