Question

By setting up and solving a proportion involving x, find the value of x for the car that you have chosen. State the type of car, the mileage, and show both the set up of the proportion and the steps to solve. Include units with your answer.

How would I do this problem? What formula do I use?

Answer 1

Is this really college algebra?
However, suppose you take a car and assign it the value x, for instance, beacuse of it being the xth car you encounter on the street. Suppose you've looked up any setting of its. It is called y (u), where the (u) shall denote the unit of the measurement.
Then reason as follows:
y (u) = k (u) * x, where k (u) = y (u) / x;
You see, it is a pretty easy calculation trick.

Answer 2

let x be the number of miles driven on 60 gallons of gas. by setting up and solving a proportaion involving x. find the value of x for the car that you chosen. what milleage and show both the set up of the proportaion and the steps to solve. include units with your answer?
