Answer:
5 large pieces of fabric.
Step-by-step explanation:
Length of each side of a square piece of fabric = yard
Area of a Square = Length X Length
Area of one square piece of fabric = X
=
square yard.
To make one scarf, Doris uses 6 square pieces.
Area of one scarf = square yard
Each large pieces of fabric is one-third yard long and 2 yards wide.
This is clearly a rectangle,
Area of a Rectangle = Length X Width
Area of each large piece of fabric= square yard.
Since the Area of one scarf is equal to the area of each large piece of fabric, in order to make 5 scarves, Doris would need 5 large pieces of fabric.
For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
We multiply both sides of the equation by -1.
