Martin decided to buy 3 bags of grapes weighing 4 1 5 pounds each. how much did all 3 bags of grapes weigh?

pounds

Step-by-step explanation:

Martin decided to buy 3 bags of grapes.

The weight of each bag = pounds

We have to calculate the weight of all 3 bags of grapes.

So we multiply to 3

= ×

=  

= pounds

The weight of all 3 bags of grapes were   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
