4 gallons of gasExplanation:Since y = 86. y+6 = 23x. Then the equation becomes 86+6 = 23 x. When you solve this you will get x = 4. In other words, this car consumes 4 gallons of gas to 86 miles away. In other words, this car's gas (fuel) efficiency is 4.65 gallons of gas per one hundred mile.

Step-by-step explanation:
Answer:
y has the greatest value.
Step-by-step explanation:
1.23w = t
Divide both sides by 1.23.
![w=\frac{t}{1.23}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7Bt%7D%7B1.23%7D)
--- (1)
1.01x = t
Divide both sides by 1.01.
![x=\frac{t}{1.01}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bt%7D%7B1.01%7D)
--- (2)
0.99y = t
Divide both sides by 0.99.
![y=\frac{t}{0.99}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bt%7D%7B0.99%7D)
--- (3)
From (1), (2) and (3), it is clear that y has the greatest value.
