Example 0.777777
x = 0.77
10(x = 0.77) ----(10 because it is repeating by the tenth digit. if repeating by 2 digits like 0.2828, you'll multiply by 100)
10x = 7.77
-(x = 0.77)
9x = 7.00
x = 7/9
X = 2
y = 1
You can get this by replacing the y in the second equation with the 3x - 5 from the first. Then solve for x. Once you have that value, you can solve for y.
You need the total of square feet of the mural before you can divide 50 square feet to it and get your answer of how many pints of paint you will need.
For example.
Mural size is 2800 square feet
1 pint per 50 square feet
Work out problem.
2800 square feet ÷ 50 square feet= ?
= 56 pints of paint
