9) Aunt Rosie made 50 pies for Mardi Gras. She made 10 apple pies.
She made 12 pecan pies.
She made 8 chocolate cream pies.
What percent of the pies were pecan?

24 percent

Step-by-step explanation:

Multiply 50 by 2 to get the standard numbers of percentile. You can then multiply all the other numbers (10, 12, 8) by 2. Do this to the 12 pecan pies and you get 24. 24 percent!

Hope this helped! Please mark me as the brainliest!

step-by-step explanation:

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
