6 dollars per hour
Step-by-step explanation:
We can set up and solve an equation to answer this question. For this problem, let x stand for the amount he earned per hour. The equation that represents this situation is 3.2x + 4.3x = 45. The first term represents monday and the second represents tuesday. When these add up they should equal 45 because that is the total amount he made. To find his pay per hour, solve for x.
First, combine the like terms
Next, divide both sides by 7.5

Answer:
Area = 
Step-by-step explanation:
The function is the area function of a rectangle.
Area of Rectangle = Length * Width
Length of fabric scrap = 5x
Length of rectangular patchwork will be 5x + 3
and
Width of fabric scrap = 2x
Width of rectangular patchwork will be 2x + 5
THus, Area = (5x+3)(2x+5) square feet.
Let's expand:
