Given that y varies directly as x and y = 18 when x = 6

sergey [27]

Answer: y = 15, x = 10

<u>Step-by-step explanation:</u>

NOTE: "varies directly" is of the form $\dfrac{y}{x}=k$ where k is the constant of proportionality.

First, input the given x and y-values to find k

$\dfrac{y}{x}=k\qquad \qquad \text{Given: y=18, x=6}\\\\\dfrac{18}{6}=k\\\\\boxed{3=k}$

Next, input the given value and k = 3 to solve for the missing variable.

$x = 5\\\\\dfrac{y}{5}=3\\\\\large\boxed{y = 15}\\\\\\y=30\\\\\dfrac{30}{x}=3\\\\\dfrac{30}{3}=x\\\\\large\boxed{10 = x}$
