Answer:
2 1/20
Step-by-step explanation:
It was trick math problem and I was working it out, so mad I didn't pay attention to the numbers more closely. :)
There are two 3/8 but one is negative so they cancel each other out
So you have now (-4/5) + 5/4
Find the least common multiple they have.
In this case 20
-4/5 = x/20 = 16/20
5/4 = x/20 = 25/20
So now add them both together
16/20 + 25/20 = 41/20
Find the least common factor for both the denominator and numerator of 41/20
41 is a prime number so
41/20 is an improper fraction
Divide 41 by 20 to get 2 1/20
= 39.84
:
100^2=251
10000=251
ℎ
251 ℎ
10000/251=251/251
39.84=1
39.84=
5.4 because you set up a proportion 7/19=2/x, 19*2=38, 38/7=5.4285, rounded you get 5.4
<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
