5. Jin ran 15.2 miles over the weekend. He ran 6.75 miles on Saturday. How many miles did
he run on Sunday?

8.45 miles

Explanation:

Since we know that overall he ran 15.2 miles on the weekend and on Saturday he ran 6.75, we can subtract 6.75 from 15.2 to find out how much more he ran on Sunday.

Step-by-step explanation:

answer is:

1.75 pounds

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
