A store is having a sale on almonds and jelly beans. For 4 pounds of almonds and 8 pounds of jelly beans, the total cost is $21. For 2 pounds of almonds and 3 pounds of jelly beans, the total cost is $9. Find the cost for each pound of almonds and each pound of jelly
beans.

3.50 for the almond 1.25 for he jelly bean

Step-by-step explanation:

Let x = number of pounds of jelly beans

      y = number of pounds of almonds.

Then, 4x + 8y = 33

          2x + 3y = 13

Multiply the second equation by -2 to get the system:

4x + 8y = 33

-4x - 6y = -26

Adding the equations, we get 2y = 7.  So, y = 3.5

Substitute for y in either of the given equations:  2x + 3(3.5) = 13

                                                                                     2x + 10.5 = 13

                                                                                                 2x = 2.5

                                                                                                   x = 1.25

ANSWER:  a pound of jelly beans costs $1.25 and a pound of                                almonds costs $3.50.

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
