Idon’t know what to do for #4. well i don’t know what to put for another equation. i dont need solving i just need doing another equation

Let s = #small notebooks

Let L = #large notebooks

We Can set up two equations from the info given.

s + L = 6           bought 6 notebooks total

8s + 10L = 56    spent $56

Solve equation 1 for one variable.

L = 6-s

Plug 6-s in equation 2 in place of L

and solve for s

8s + 10(6-s) = 56

8s + 60 - 10s = 56

-2s + 60 = 56

-2s = -4

s = (-4)/(-2)

s = 2

 We know s+L = 6 and s=2

2+L = 6

L = 4

 4 large notebooks and 2 small notebooks

were purchased

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

the answer would be c:   ax + b = ax + c
