Question

Want a medal?
I need to create 3 linear equations for three objects.
A baseball, a basketball, and a football helmet.
I don't know where to begin.
Then I need to create a Literal Inequality using roller blades?
I know I need to create variables for the objects so I guess I'll use the first letter but I don't know how to creatively make linear equations for each of these objects..Please help<3
This isn't multiple choice or anything I just need to create literal equations with all variables in the formula in the correct positions. Final solution needs to be correct also
