Question

Constant of proportionality​

Answer 1

9.1) k = 4.6

9.2) k = 6

Explanation:

9.1)
`115 = k(25)`

To find constant of proportionality, k, divide both sides by 25

`(115)/(25) = (k(25))/(25)`

`4.6 = k`

Constant of proportionality, k = 4.6

9.2)
`15 = k(2.5)`

To find constant of proportionality, k, divide both sides by 2.5

`(15)/(2.5) = (k(2.5))/(2.5)`

`6 = k`

Constant of proportionality, k = 6
