Gas mileage is the number of miles you can drive on one gallon of gas. a test of a nissan car results in 450 miles on 10 gallons of gas.

a. what is the car's gas mileage?

b. how far could you drive with 60 gallons of gas?

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
