Which expression represents 50 divided by an unknown number? he me 80 points a.50.r b.50-r c.50+r d.50/r

Since all the answer have the letter r in it, r would be the unknown number.

In math the "/" line represents division.

So 50 divided by an unknown number would become 50/r/

The answer is D.

D  50/r

Step-by-step explanation:

50 divided by an unknown number

Let the unknown number be r

50/r

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

it goes right
