<u>Answer:</u>
First car: 35 gallons
Second car: 15 gallons
<u>Step-by-step explanation:</u>
Assuming
to be the gas consumed by 1st car and
to be the gas consumed by 2nd car.
We know that:
Distance traveled = fuel efficiency × gas consumed
![20x+35(50-x)=1225](https://tex.z-dn.net/?f=20x%2B35%2850-x%29%3D1225)
![20x+1750-35x=1225](https://tex.z-dn.net/?f=20x%2B1750-35x%3D1225)
![35x-20x=1750-1225](https://tex.z-dn.net/?f=35x-20x%3D1750-1225)
![15x=525](https://tex.z-dn.net/?f=15x%3D525)
![x=35](https://tex.z-dn.net/?f=x%3D35)
So
Therefore, first car consumed 35 gallons while second car consumed 15 gallons.
Answer:
x = -8
Step-by-step explanation:
1/4x+2=-5/8x-5
Add 5/8 x to each side
1/4x + 5/8 x+2=-5/8x + 5/8x-5
1/4x + 5/8x +2 = -5
Subtract 2 from each side
1/4x + 5/8x +2-2 = -5-2
1/4x + 5/8x = -7
Get a common denominator of 8
1/4 *2/2 x + 5/8x = -7
2/8x + 5/8x = -7
7/8x = -7
Multiply each side by 8/7
8/7 * 7/8x = -7*8/7
x = -8
