At the market, 8 batteries cost $10
How much do 6 batteries cost?

7.50

Step-by-step explanation:

We can use proportions to solve

8 batteries         6 batteries

=

10 dollars           x dollars

Using cross products

8x = 6*10

8x = 60

Divide each side by 8

8x/8 = 60/8

x =7.50

tube or goog would be a great resource to with that question

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
