Which of the following is the key difference between the U.S. system of government and a multiparty system of government?
aivan3 [116]

Answer:

The formation of a "coalition" government.

Explanation:

According to a different source, these are the options that come with this question:

  • The election of a prime minister.
  • The organization of government under a constitution.
  • The formation of a "coalition" government.
  • The influence of a dictator.

One key difference between the U.S. system of government and a multiparty system of government is that in the U.S. system, coalition governments cannot be formed. A coalition government is a form of government in which political parties cooperate. This reduces the risk of dominance of a single party. Coalitions are usually formed in countries that operate under the principle of proportional representation, as most of the time, no political party can achieve a majority on its own.

What is | -7.9 ?<br> help
Tamiku [17]
I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!
