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.

good job you smart son of a gun you are smarter that einstein. 7

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
