Answer:
5x
Answer Explained:
All the x’s add up together to make 5x
The slope of the line = 1/2
Answer:
9/56
Step-by-step explanation:
the odds of the first one being green is 3/8
the odds of the second one being blue is 3/7 because one was removed
multiply these to find the probability
3/8*3/7=9/56
x is less than or equal to -4 or x is greater than or equal to 5
x <= -4 or x>= 5
There is no intersection of both inequalities when we graph it in number line So, we write the interval notation separately for each inequality
for x<=-4 , x starts at -4 and goes to -infinity because we have less than symbol. Also we have = sign so we use square brackets
Interval notation is (-∞ , -4]
for x>= 5 , x starts at 5 and goes to infinity because we have greater than symbol. Also we have = sign so we use square bracket at 5
Interval notation is [5 , ∞)
Now combine both notation by a 'U' symbol Union
(-∞ , -4] U [5 , ∞)

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°.
