Respuesta :

The volume occupied by a 350 pound sphere is 2.33 ft³.

Equation

Equation is an expression used to show the relationship between one or more numbers and variables.

Let y represent the weight of the sphere in pounds and x represent the volume in feet³, hence:

y = 150x

For a 350 pounds sphere:

350 = 150x

x = 2.33 ft³

The volume occupied by a 350 pound sphere is 2.33 ft³.
