Answer:
400/π
Step-by-step explanation:
Well, we know that the formula for circumference is πd. (d is the diameter) Then, we set up the equation 'πd = 400'. Now, simplifying for d, we get d = 200/π.
5(n - 2) = n + 7
5n - 10 = n + 7
5n - n = 7 + 10
4n = 17
n = 17/4 or 4 1/4 <== ur answer
check..
5(n-2) = n + 7
5(17/4 - 2) = 17/4 + 7
5(17/4 - 8/4) = 17/4 + 28/4
5(9/4) = 45/4
45/4 = 45/4 (correct)
Answer:
x = 41
Step-by-step explanation:
(2x+20) + (2x-4) = 180 degrees
4x+16 = 180 degrees
4x = 164
x = 41
The two sides are supplementary and add up to 180 degrees.
