Answer:
We need 5 yards green felt and 4 yards blue felt for each quilt.
<em>Step</em><em>-</em><em>wise</em><em>:</em>
Let length of green felt be 'x' , length of blue felt be 'y' and and number of quilts be z.
If Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts.
⇒15x+12y=3z15x+12y=3z
Now, divide both sides by 3 , we get
5x+4y=1z5x+4y=1z
<em><u>Therefore, we need 5 yards green felt and 4 yards blue felt for each quilt</u></em>.
120 is your answer cause half 120 is 60
"the following" of what? I think you are missing the list
The answer is: R = P + C
Steps:
First, move r to the left side of the equation and change its sign.
-r + p = - c
Then, move p to the right side and change its sign.
-r = -c - p
Multiply both sides of the equation by -1. This will change the variables back to positives, because any expression multiplied by -1 equals its opposite.
-1(-r) = -1(-c) -1(-p) =
r = c + p (don’t forget to change the sign)
So, your final solution is: r = c + p or r = p + c
