Yu-jun's craft store sells 3 handmade
barrettes for $9.99. which expression can be
used to find the total cost c of x barrettes?
h c = 3.33x
g c = 9.99x
j c = 3: 33
f c = 9.99

C =3.33x

Step-by-step explanation:

The cost of 1 barrette is

9.99/3  sine it is 9.99 for 3 barrettes

or 3.33 per barrette

We want x barrettes

or 3.33*x

C is the total cost

C =3.33x

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
