Hree girlfriends (karen, tara, and chelsea) each buy ice cream and paper back novels to enjoy on hot summer days. ice cream costs $5 per gallon and paperback novels cost $8 each. karen has a budget of $80, tara has a budget of $60, and chelsea has a budget of $40 to spend on these two goods. which girl can afford to purchase 8 gallons of ice cream and 5 paperback novels?

  Karen

Step-by-step explanation:

8 gallons of ice cream at $5 per gallon will cost $40. 5 paperback novels at $8 per novel will also cost $40. Only Karen has a budget sufficient to cover the $40+40 = $80 total.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

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
