Answer:
[tex]x=8((m*p)/y)[/tex]
Step-by-step 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:
[tex]x=constant value((m*p)/y)[/tex]
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:
[tex]x=8((m*p)/y)[/tex]
If you replace:
[tex]x=8((2*0,5)/4)[/tex]
The result is x=2
