1. X=2+1/2y+1/2z
2. X=-1+2y+z
3. X=16/3-1/3y-1/3z
Answer:
5 feet (60 inches) proportional to 2 inches is a 30:1 relationship.
15 feet (180 inches) in real life should equal 6 inches on the diagram.
180 divided by 30 = 6
Step-by-step explanation:
Answer:
113.1cm^2
Step-by-step explanation:
We know the area for a circle is pi * r^2, where r is the radius. We know the diameter, so all we need to do to find the radius is half the distance of the diameter, which would then be 6 cm. We plug in 6 as r, we get 36pi cm^2 as our exact answer. And a good approximation would be 113.1 cm^2.
Answer:
z > 13
Step-by-step explanation:
Subtract 9 from 22.
z > 13
