type your answer and then click or tap done.
the value of y is 120 when x is 4 and w is 2.
what is the constant of variation?
k = \boxed{}

Explanation:

Step1: Substitute values into formula

$120 = k \times 4 \times 2$

Step2: Calculate product of x and w

$4 \times 2 = 8$

Step3: Solve for k

$k = \frac{120}{8} = 15$

Answer:

15
