Answer:

See below and attached.

Step-by-step explanation:

Draw a rectangle.

Divide it in half.

Divide each part in half again.

Lastly, divide each part again in half.

This will give a total of 8 sections.

Project a uses 1/2 of the fabric. This means it will use 4 out of the 8 pieces.

Project b uses 1/4 of the fabric. This means it will use 2 out of 8 pieces.

So the fabric that is left is 1 - 1/2 - 1/4 = 1/4.

You can find the amount left for any number of yards of fabric by taking f(x) = x/8 - 3/4

Solve by substitution 3x+y=3 and 7x+2y=1
balu736 [363]

3x + y = 3

7x + 2y = 1

First isolate one of the variables (x or y) in one of the equations.

Isolate "y" in the first equation(because it is the easiest to isolate) and substitute it into the second equation.

3x + y = 3      Subtract 3x on both sides

3x - 3x + y = 3 - 3x

y = 3 - 3x


7x + 2y = 1

7x + 2(3 - 3x) = 1     [since y = 3 - 3x, you can substitute (3-3x) for "y"]

Multiply/distribute 2 into (3 - 3x)

7x + (3(2) - 3x(2)) = 1

7x + 6 - 6x = 1

x + 6 = 1     Subtract 6 on both sides

x = -5


Now that you know "x", substitute it into one of the equations (I will do both)

3x + y = 3

3(-5) + y = 3       [since x = -5, you can plug in -5 for "x"]

-15 + y = 3    Add 15 on both sides

y = 18


7x + 2y = 1

7(-5) + 2y = 1

-35 + 2y = 1     Add 35 on both sides

2y = 36     Divide 2 on both sides

y = 18


x = -5, y = 18  or  (-5, 18)
