Answer:
10
Step-by-step explanation:
2(x+9)+142=180 corresponding angles are equal and angles on a straight line=180
2(x+9)=180-142
x+9=38/2
x=19-9
x=10
3x - 14 = 2x + 25
+14 +14
3x = 2x + 39
-2x -2x
x= 39
therefore x is 39. If you want to find the exact angel, just substitute 39 into x, solve for it and it should give you the exact angel.

Answer:
2/3
Step-by-step explanation:
First find what fraction of caffeine is hydrogen, 1 - 3/6 - 2/6 - 1/6 = H meaning hydrogen = 0/6 or 0.
Next add O + N + H which is 3/6 + 1/6 + 0/6 which is 2/3.
Answer:
D.
Step-by-step explanation:
I graphed it. They are both not in the same qudrant because both their x and y values are opposites. This led me to believe that they were in quadrants digaonal of each other, meaning the answer was D, because if you flipped the point across the x or y axis and then flipped it again across the other axis, it would be that point. Just in case, I graphed it. Please tell me if I'm wrong :)
