Answer:
2
Step-by-step explanation:
Given two points on the line, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 - -3)/(3 - -2)
= (7+3)/(3+2)
= 10/5
=2
Let the number of degrees that the counterclockwise particles moves through be d degrees.
The number of degrees that the clockwise particle moves through will be 360-d degrees:. The times taken to where they meet is the same for both particles.
Rate = degrees / time , so:-
3 = d/ t ; giving t = d/3
42 = 360- d / t so t = (360 - d) / 42
Equating values of t:-
d/3 = (360-d) / 42
42d = 1080 - 3d
d = 1080 / 45
= 24 degrees (answer)

Answer: Choice C
Step-by-step explanation: The correct sum of 6 feet 10 inches and 8 feet 9 inches is 15ft 7 inches.
In order to calculate this, you will first add the inches.
10 inches plus 9 inches equals 19 inches, which is 1 ft 7 inches.
Next, add the feet - 6 ft plus 8 ft equals 14 ft.
To finish, 14 ft plus 1 ft 7 inches equals 15 ft 7 inches, which is choice c.
