Answer:
![r = - \frac{5}{3} = 1 \frac{2}{3} = - 1.6](https://tex.z-dn.net/?f=r%20%3D%20%20-%20%20%5Cfrac%7B5%7D%7B3%7D%20%20%3D%201%20%5Cfrac%7B2%7D%7B3%7D%20%20%3D%20%20-%201.6)
Step-by-step explanation:
![- 8r - ( - 2r - 3) = 13](https://tex.z-dn.net/?f=%20-%208r%20-%20%20%28%20-%202r%20-%203%29%20%3D%2013)
![- 8r + 2r + 3 = 13](https://tex.z-dn.net/?f=%20-%208r%20%2B%202r%20%2B%203%20%3D%2013)
![- 6r + 3 = 13](https://tex.z-dn.net/?f=%20-%206r%20%2B%203%20%3D%2013)
![- 6r = 13 - 3](https://tex.z-dn.net/?f=%20-%206r%20%3D%2013%20-%203)
![- 6r = 10](https://tex.z-dn.net/?f=%20-%206r%20%3D%2010)
![\boxed{\green{r = - \frac{5}{3} = 1 \frac{2}{3} = - 1.6}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cgreen%7Br%20%3D%20%20-%20%20%5Cfrac%7B5%7D%7B3%7D%20%20%3D%201%20%5Cfrac%7B2%7D%7B3%7D%20%20%3D%20%20-%201.6%7D%7D)
836, because 484 divided by 22 is 22, so each gallon can do 22 miles. 38 times 22 is 836.
