Answer:

n=14/5

Step-by-step explanation:

4n+n-16=-2

We move all terms to the left:

4n+n-16-(-2)=0

We add all the numbers together, and all the variables

5n-14=0

We move all terms containing n to the left, all other terms to the right

5n=14

n=14/5

Can somebody PLEASE help !!!

Answer:

Elissa needs 4 quarts of paint, or 1 gallon.

Step-by-step explanation:

Elissa's room is in the shape of a rectangular prism.  Assuming that she will only be painting the walls and not the floor or ceiling, you just need to calculate the area of the four walls - front and back and side to side.  Based on the dimensions given, the area of Elissa's front and back walls are 8 ft x 9 ft or 72 ft² for each wall.  Since there are two, we take that area times two: 72 x 2 = 144 ft².

Elissa's side walls are 8 ft x 13 ft or 104 ft² for each wall.  Since there are two, we take this area times two:  104 x 2 = 208 ft².

To find the total area needed to paint, we add all four walls:  144 + 208 = 352 ft².  Since a quart of paint covers 100 ft² and a gallon covers 400 ft², Elissa can either purchase 4 quarts of paint or 1 gallon to paint her bedroom.
