The quantities x and y are proportional. Find the constant of proportionality (r) in the equation y=rx

r =

Step-by-step explanation:

The proportional equation is

y = rx ( divide both sides by x )

= r

Substitute any ordered pair from the table

Using (14, 7 ) , then

r = =

66answer:

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
