Question

x = 21 and y = 6 solve for the proportionality.

Answer 1

Answer: 3.5

Step-by-step explanation: To solve for the proportionality between x = 21 and y = 6, we must identify the constant of proportionality in that x = ky. We can construct our equation accordingly:

$21 = 6k$

When we divide by the coefficient (6), we find:

$\dfrac{21}{6} = 3.5$

$\dfrac{6}{6} = 1, \ or \ k$

Finally, we find that 3.5 = k. Therefore, the constant of proportionality amounts to 3.5.
