Suppose that y varies directly as x, and y = 10 when x = 25. What is the value of y when x = 6?

Question

Need equation and x=6 Maybe the explanation also. SO ya

Answer 1

If y varies directly as x the ratio of the 2 quantities will be constant ( as x increases y will do so as well) So can set up a proportion 25/10 = 6/x and solve for x

25x=60 x= 2 2/5
