Answer:
<h2>10 inches</h2>
Step-by-step explanation:
Given the circumference= 30 in
we know that the formula for circumference is

Approximately the diameter is 10 inches
Answer:
w = -7z/2
Step-by-step explanation:
Our goal is to isolate w
1. subtract 3w from both sides to get 2w+9z = 2z
2. Subtract 9z from both sides to get 2w = -7z
3. Divide both sides by 2 to get w = -7z/2
We cannot simplify further, so this is our answer.
Supplementary angles add up to 180 degrees, so look for two angles by each other that add up to 180 degrees.
Hope this Helps!
