Please help me with my homework i will give you alot of points

see below

Step-by-step explanation:

7.    1/3 ( n+2) = 5

Multiply each side by 3

n+2 = 5*3

n+2 = 15

Subtract 2 from each side

n+2-2 = 15-2

n = 13

8.x = bills

He started with 300 and paid 1/4 of the bills and ended up with -50

300 - 1/4 x = -50

Rearranging the order on the left

-1/4x + 300 = -50

(A)

Step-by-step explanation:

I "reversed" this problem to find the equation that works for it.

The balance was originally $300. If he's now at a balance of -50$ after paying off of his bills, then of his bills are $350, since .

If    of his bills are $350, then his full bill is $.

So I tested each equation, where to see if the equation worked out.

For a:

-350 + 300 is indeed -50, so I knew this equation works.

Hope this helped!
