Answer:
<h2>One solution.</h2>Step-by-step explanation:
The given question is
<em>Does the following system have One Solution, No Solution, or Infinite Solutions. </em>
<em /><em />
<em />
<em />
To solve this system, we just need to multiply the first equation by -1, and then sum those equations.
Then, we use this value to find the other one
As you can observe, the system of equations have a unique solution.
Therefore, the answer is one solution.
first polygon
ext. angle=180°-120°
=60°
n=360°/60°
n=6
second polygon
n=2(6)=12
ext. ang= 360°/n = 360°/12° = 30°
int. ang = 180°-30°= 150°
answer is C
The quotient is 5x+3 and the remainder is 5/x-1
