Which of the following question would use the calulation 7 x 1/8 A: a pizza is cut into 8 slices beth eats 7 of them. what fraction of the pizza is left

B: A pizza is cut into 7 slices beth eats 8 of them what fraction of the pizza is left?

C: A pizza is cut into 7 slices beth eats 8 of them. what fraction of the pizza did beth eat

D: a pizza is cut into 8 slices beth eats 7 of them. what fraction of the pizza did beth eat

The answer is D: a pizza is cut into 8 slices Beth eats 7 of them. what fraction of the pizza did Beth eat.

Step-by-step explanation:

If there are 8 slices and 7 of them have been eaten, that means 7/8 have been consumed.

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
