Assume that y varies directly with x . Ify = 18when x = 6 , findywhen x = 5 . Write and solve a direct variation equation to find the answer. y =

y = 15

Step-by-step explanation:

It's given in this question that y varies directly with x.

That means, y ∝ x

⇒ y = kx (where k is the proportionality constant)

If  y = 18 when x = 6,

⇒ 18 = 6k

⇒  k = 3

Therefore, relation between x and y is,

y = 3x

From this relation, if x = 5

y = 3×5

y = 15

Therefore, for x = 15 value of y will be 15.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
