First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.
2x+7=3x-7
x=14
Then, since 2x+7 and 12y+1 equals 180, put it together to find y:
(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12
So, x=14 and y=12. Your answer should be C!

Answer:
At least 39200 students.
Step-by-step explanation:
Given that there are 196 countries in the world, and each country would have at least 200 students in a university.
For each country to have at least 200 students in the university, then;
Number of students enrolled in the university = number of required students x number of countries
= 200 x 196
= 39200
At least, 39200 students must be enrolled in the university. Provided that the admission procedures are conditioned for the purpose.
the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
