Answer: 22.5 yards
Step-by-step explanation:
There are a total of 20 parts yarn. This means that 3/20 of the carpet is silver. So in order to compare this to the 150 meters of total yarn, you would set up this equation:
3/20 = x/150
Next, you cross multiply:
3*150 = 20*x or simplified would be 450 = 20x
Next, you divide both sides by 20 to get x by itself.
450/20 = 22.5, so x is equal to 22.5
This means you have 22.5 yards of silver in the carpet.
1) Draw the coordinate plane
2) Draw the line y = - 2
It is a line parallel to the y axis, two units below the origin
3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.
