Question

Y varies directly with x, and 84 when x is 16 what’s is the consta probortionality

Answer 1

Answer:

5.25

Step-by-step explanation:

      y varies directly with x

            y ∝ x

Now, let us introduce the constant of proportionality which is k;

           y  = kx

If y = 84 and x = 16; what is k;

           84  = 16k

            k  = $\frac{84}{16}$   = 5.25
