Given: The odds of winning a contest are 3:7
To find: probability of winning the contest
Solution:
Probability refers to chances of occurrence of an event.
Odds are defined as (chances for success) : (chances against success)
Probability of winning = (chances for success) : (chances for success + chances against success)
As odds of winning a contest are 3:7,
(chances for success) : (chances against success) = 3:7
So,
Probability of winning the contest = 
What are the numbers given?
Answer: 3x+4=5x
Step-by-step explanation:
Three times a number: 3x
Increased by 4 then means that you are adding 4 to that number after it is multiplied: 3x+4
Is equal to 5 times the number means that you have to set the equation equal to 5x: 3x+4=5x

Answer:
The new points would be (-7, -1), (-3, -2) and (-8, 1). The angle would not change
Step-by-step explanation:
When you rotate points by 180 degrees, you simply change the sign on the ordered pairs. This will give you the new points.
Also, spinning the points will not change the angle between them. Therefore it stays the same.
