Question

The value of y is directly proportional to the value of x when x=512 y=128 what is the value of y when x=64

Answer 1

Answer: y=16
explanation: y=128 when x=512, so to get the value of y, you need to divide 512/64=8. dividing 512(x) by 8 times gets 64, so you need to divide 8 on the other side(y). 128/8=16. hope this helped!
