The United States of America mostly and maybe Canada
Answer:
Step-by-step explanation:
Given that line passes through (0,0) and (2,1)
(Note that any two points are sufficient to determine the equation of the line)
The slope = change in y/change in x = (1-0)/(2-0) = 1/2
Hence answers are:
Variable y varies directly with x. (if x increases y also increases and vice versa)
The constant of variation = slope of line = 1/2
The constant of variation is 2 is wrong since slope = 1/2
The variable y does not vary directly with x is wrong since when x increases by 1 unit y increases by 1/2 unit for all real x.

Answer:
x = 20
Step-by-step explanation:
The two indicated angles are vertical angles and vertical angles are equal
3x+50 = 6x-10
Subtract 3x from each side
3x-3x+50 = 6x-10-3x
50 = 3x-10
Add 10 to each side
50+10 = 3x-10+10
60 = 3x
Divide each side by 3
60/3 = 3x/3
20 =x

As there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.
Since a group of friends played chess, and each person played exactly one game with each other in the group, and out of the total number of games played, 3 games were played between a boy and a boy, and 6 games were between a boy and a girl, to determine how many games were played between a girl and a girl, the following calculation must be performed:
- 2 players = 1 match
- 3 players = 3 games
- 6/3 = 2
Therefore, as there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.
