Answer:

one binder for $3.70

Step-by-step explanation:

The cost of 5 binders and 3 folders = $23.00

The cost of 5 binders and 1 folder = $20.00   [ 2 folders less ]

Cost of 2 folders = 23 - 20 = $3.00

Cost of 1 folder = \frac{3}{2} = $1.50

The cost of 5 binders = 20.00 - 1.50 = $18.50

The cost of 1 binder = \frac{18.50}{5}

                                = $3.70

The cost of one binder is $3.70

HELP! My teacher didn't teach half the material! How do I do this!?!?!?!
Sladkaya [172]

Answer:

<h2>x=-0.3</h2>

Step-by-step explanation:

1-(-7.2x+3.5)=5+3(7.4x-1) first parenthesis

1+7.2x-3.5=5+22.2x-3  

7.2x-2.5=2+22.2x (x on one side and numbers on other)

22.2x-7.2x= -2-2.5

15x=4.5 divide by 15

x=-4.5/15

<h2>x=-0.3</h2>

If the average of nine consecutive integers is zero, what is the largest integer?
Orlov [11]

Answer:

4

Step-by-step explanation:

The average of the consecutive integers is 0, so the middle number must be 0, with 4 numbers less than 0 and 4 numbers greater than 0.

-4, -3, -2, -1, 0, 1, 2, 3, 4

So the largest integer is 4.
