I think the answer is a scalene triangle
Answer: a = -5
Step-by-step explanation:
2(a+3)=-4
Distribute
2a+6=-4
subtract the six with the four and you get -10
-6-4=-10
now divide 2a with -10
you get a= -5
you can plug the answer in
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.
