58% is the answer. 7 dividing 12= 0.5833333
you much move the decimal over two places and you would get 58%
14x13= 182 sq ft
183 sq ft = 20.22 sq yd
28.95x20.22=
5853690
move the decimal four spaces from the right and round up
585.37 is the answer
5 yellow marbles out of total of 17 marbles so 5/17
Answer: 5 (8-9x)
Step-by-step explanation:
25 x 2 - 45 x -10
50 - 45 x -10
40 - 45x
Set up the following equations:


110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.
We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

Divide both sides by 2 to get L by itself:
The length of the rectangle is 65 feet.Plug this value into the second equation:

Add W to both sides:

Subtract 20 from both sides:
The width of the rectangle is 45 feet.
