Jodi car used 12 gallons of gas to travel 456 miles. how many miles did her car travel per gallon of gas

38 miles

Step-by-step explanation:

Given : Jodi car used 12 gallons of gas to travel 456 miles.

To Find: how many miles did her car travel per gallon of gas?

Solution:

No. of miles covered in 12 gallons of gas = 456

So, No. of miles covered in 1 gallon of gas =

                                                                      =

So, No. of miles covered in 1 gallon of gas is 38 miles

Hence Her car travel 38 miles per gallon of gas

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
