Events are mutually exclusive only if they cannot both be true.
Only C is alright.
4 is a multiple of two so it can't be right.
Same logic works for B.
And then 2 is prime so then D is out too.
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!
It would first be 0.7 and then 1.1
