Question

When x is 2, y is 4, p is 0.5, and m is 2. If x varies directly with the product of p and m and inversely with y, which equation models the situation?

Answer 1

Can you elaborate please? What does p and m mean?

Answer 2

`x=8((m*p)/y)`

Explanation:

You have that x varies directly with p*m (which means that if the result of m*p increase, x increase)

And you have too that x is inversely with y (which means that if y increase, x decrease).

Then you must get:

`x=constant value((m*p)/y)`

If the problem says that x is 2, y is 4, p is 0.5, and m is 2

the constant value should be 8, in this way:

`x=8((m*p)/y)`

If you replace:

`x=8((2*0,5)/4)`

The result is x=2
