Answer:
defines the gallons of the gas consumed by the old car in one year.
Step-by-step explanation:
If I purchase a car, I will definitely concentrate on a factor that is gas consumed by the car in a year.
As per statement given in the question if gas is $3.45 per gallon and I drive an average of 18000 miles per year.
If x miles per gallons is the average of the old car and y miles per gallons is the average of of new car.
Then total difference in gallons of the gas consumed by the old and new cars will be represented by the equation.
g(x) = 3.45 - 3.45
Here, defines total number of gallons of the gas consumed by the old car in one year.
The answer would be the top right device.
Answer:
5.
Step-by-step explanation:
7x=35; ⇔ x=5.
Let's forget for the tie being the cost ($3.5)of the 1st fifth of a mile:
Taxi charge excluding $3.5, is $13.95 - $3.5 = $10.45.
If each of the 5th (1/5) of a mile costs $0.55, then with $10.45 we can drive:
10.45/0.55 = 19 fifth of a mile. Add to that the 1st fifth = 20 fifth of a mile
20 fifth = 20 x 1/5 = 4 miles (answer)
