<em><u>Complete Question:</u></em>
The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?
<em><u>Answer:</u></em>
The numerator of fraction is -360
<em><u>Solution:</u></em>
Given that,
<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>
We have to solve the equation for "n"
Rearrange the equation
Thus the numerator of the fraction is -360
Well, I can’t see your choices, but hopefully one looks something like this:
1.25x = 11.25
Or
x = 11.25/1.25

Answer:2/5
Step-by-step explanation:
3/5 of 45
3/5 x 45
(3x45)/5
135/5=27
45-27=18
What of fraction of 45 equals 18
Let the fraction be y
y of 45=18
y x 45=18
Divide both sides by 45
(y x 45)/45=18/45
y=2/5
Answer:
5
Step-by-step explanation:
- (4n+5)-n/20=1
- cross multiply:(4n+5)-n=20
- 4n+5=20+n
- 4n-n=20-5
- 3n=15
- Divide both sides by coefficient of n
- n=5
