(2x + 4) - (-x + 5)
= (2x + 4) -1(-x + 5)
= 2x + 4 + x - 5
= 2x + x + 4 - 5
= 3x - 1.

We let x represent number 1 and let y represent number 2. In this case, the first statement is translated into an expression: y - x = 25 while the second statement is expreesed as x = y/6. Solving the two euqations simultaneously, y is equal to 30 and x is equal to 5. hence, answer is 5
Answer:
The width would be 10 inches.
Step-by-step explanation:
To find this, start by labeling the width of the rectangle as x. Now we can express the length as 3x - 5. Now use the perimeter formula and the known perimeter to find x (which is the width).
2l + 2w = P
2(3x - 5) + 2x = 70
6x - 10 + 2x = 70
8x - 10 = 70
8x - 80
x = 10
The answer is D because if you don 3/8 divided by 4 then you do Keep Flip Change which is 3/8 x 1/4 and that gives you 3/32
