Question 90375


     If y varies directly with x, and y = 54 when x = 3, find the constant of variation k

        y varies dierctly as x 

            y = k*x   where k is a constant
  
     when y = 54 and x = 3  to find k
  
           From the relation y = kx,   k = y/x = 54/3 = 18
   
   The value of k = 18
