-84 = 3(5n + 2)
 
Multiply everything in the parenthesis.

-84 = 3(5n + 2)
          3*5n + 3*2

-84 = 15n + 6 
Subtract 6 from both sides

-84 = 15n + 6 
-6                -6

-90 = 15n
Divide 15 from both sides

-90 = 15n
--------------
15       15

-6 = n

-6 is your answer.

First divide both sides by the coefficient, -84, to leave (-3 - 5p) = -176/-84 = 176/84

Then add 3 to both sides, which gives -5p = (176/84) + 3 = 62/21 + 3

Now divide both sides by the coefficient -5:

p = (125/21)/-5 = -25/21

The school cafeteria served 2,560 cups of milk in March and 1,560 cups of milk in April. How many quarts of milk did the cafeter
sergiy2304 [10]

Answer:

1,030 quarts in two months

Step-by-step explanation:

First you would add the two months together like: 2,560 + 1,560 = 4,120

Then you would divide I think 4,120 by 4 which would look like: 4,120/4

You should get 1,030.  I'm not sure if I did this right so rip ¯\_(ツ)_/¯
