Question

If x varies directly as y and x=3 when y = 8, find the value of y when x=9

Answer 1

Answer: Y =24

Step-by-step explanation:first get the constant. X=KY substituting x and y in the equation is 3=K8 Therefore K = 3/8 =0.375

If x is 9 find y when the constant k is 0.375 from the equation x=ky

Is Y = X÷K is 9÷0.375 =24.
