Answer:
12 gallons of paint
Step-by-step explanation:
Sasha can paint 400 square feet using 1 gallon of paint
If she needs to paint 4,704 square feet, then she will need to purchase 4,704 / 400 = 11.76 gallons of paint. Since she can only purchase paint in whole gallons, she will need to purchase 12 gallons of paint (we have to round up).
X + 6 = 8 + 7x
First, use the equality property to move the variable x to one side.
x + 6 = 8 + 7x
-x -x
You are left with: 6 = 8 + 6x
Use the equality property again
6 = 8 + 6x
-8 -8
-2 = 6x
Divide each side by 6: and your solution is -2/6, which simplifies to -1/3
