<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
Let first number is x
second number be y
one number is four less than a second number: x=y-4
Three times the first is 6 more than 6 times the second: 3x=6y+6
substitute x=y-4 in 3x=6y+6
3x =6y+6
3(y-4)=6y+6
3y-12=6y+6
3y-6y=6+12
-3y=18
y=-6
substitute y=-6 in x=y-4
x=-6-4=-10
so first number is -10
second number is -6

Answer:
$12.25
Step-by-step explanation:
1.6 ounces of cinnamon sticks and 9.4 ounces of cocoa. The equation for this would be 3.25s + 0.75c = t, where s is the amount of cinnamon sticks, c is the amount of cocoa, and t is the total price.
3.25s + 0.75c = t
3.25(1.6) + 0.75(9.4) = t
5.2 + 7.05 = t
12.25 = t
The total price is $12.25.
