You download 4 songs for $5. Write an equation that uses the constant of of proportionality to describe the relationship between the cost in d dollars
for s songs.

The equation is;

d = 1.25s

Step-by-step explanation:

Here, we start by getting the price of a single song

From the question;

4 songs = $5

Thus, 1 song will be $5/4 = $1.25

So the proportionality constant is $1.25 per song

To write the relationship, we have;

d = 1.25s

Where d is the cost in dollars and s is the number of songs

answer: finding the extract measurements and knowing the points

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
