Answer:
A community is usually a combination of territorially defined people, united by, for example, history, kinship, co-operation, common values and way of life. Usually, a community is made up of people living close together, but a community can also be a larger number of people who have something in common, such as nationality, ideology or interests.
In turn, political science studies the impact that politics as a decision-making system has on the life of communities. Thus, it studies how governments affect the lives of their citizens through their policies, and how citizens react to them.
Therefore, the community is ultimately the subject on which the activity of the political sciences falls, as they study their relationship with politics.
Answer:
yellow = 4
green = 2
blue = 3
red = 3
Explanation:
y = yellow marbles
r = red marbles
b = blue marbles
g = green marbles
y + r + b + g = 12
y = 1/3 (12) = 4
r = b
g = y - 2 = 4 - 2 = 2
That means...
4 + r + b + 2 = 12
<em>Combine like terms</em>
r + b + 6 = 12
<em>Subtract 6</em>
r + b = 6
<em>Because r = b, plug in b for r</em>
b + b = 6
2b = 6
b = 3
Which makes r = 3
