Answer:
x = 50
Step-by-step explanation:
The sum of exterior angles of a convex polygon is 360°.
130° + x° + 30° + 100° + x° = 360°
2x° = 100° . . . . . . . . . subtract 260° and collect terms
x = 50 . . . . . . . . divide by 2°
_____
<em>Additional comment</em>
If you reduce each side length to nothing, then you find the angles are measured around a central point. It becomes more clear that their sum is 360°.
Answer:
B. (5/2 , 7/2)
Step-by-step explanation:
The graph shows the solution to be about (2.4, 3.5), a reasonable match with choice B, (2.5, 3.5).
_____
If you consider the intercepts, you see that the first equation has intercepts at x=-2, y=1.6, and the second equation has intercepts at x=1 5/6 and y=-11. If you think about this for a minute, you realize the lines must cross in the first quadrant at a point with an x-value more than 1 5/6, and a y-value more than 1.6.

Answer:
4th option, 5 5/6
Step-by-step explanation:
8 1/2 - 2 2/3
= 17/2 - 8/3
= (51-16)/6
= 35/6
= 5 5/6
