Answer:
Your answer is going to be 34/7.
Step-by-step explanation:
In order to solve this problem, you are going to have to work backward. In the first part, you are trying to see what subtracted with 59/7 after you find that you add 22/7 to it. then subtract 30/7 from the sum. This gives you your answer.
59/7-19/7
40/7+22/7
64/7-30/7
34/7

<span>C. (8, -2) (-2, 5) (6, 0)?
I'm not totally sure.</span><span />
the sum of all the angles in a hexagon is 720°, so:
(4x-5)+117+(3x-3)+(3x+6)+118+(4x-3)=720
4x+3x+3x+4x= 720+5-117+3-6-118+3
14x=490
x= 490/14
x= 35
