Question

The value of y varies directly with x. When y = 3.5, x = 2.

What is the value of y when x is 16?

Answer 1

in order to do this problem, you have to divide 16 by 2 to see how many times x was multiplied. you would find that x was multiplied 8 times, so in order to find y, you would multiply 3.5 eight times.

y = 28 when x = 16
