You can use substitution method
x - y = 7
(x+y)^2=289
So
Since the square of their sum is 298, their sum without being squared is the square root of 289.
Hence,
x - y = 7
x + y = 17
By subtracting you get the following:
= (0) -2(y)=-10
So -2y=-10
y=-10/-2
y=5
Now, plug in y in both equations to get x
x - (5) = 7
x + (5) = 17
Multiply each equation with its opposite y variables
(5) x - (5) = 7
(-5) x + (5) = 17
= 5x -25 = 35
-5x -25 = -85
Now subtract the equations
= 10x + (0) = 120
10x = 120
x = 120/10
x = 12

Why was slavery a paradox in the United States? Why did most blacks not want to go to Africa during the colonization movement? W
Mekhanik [1.2K]

Answer and Explanation:

Slavery in the United States was a paradox because it was stated in the constitution that all men are created equal, yet the same document contradicted it and there were laws such as the Virginia law passed in October 1705, stating that if a master was to kill a slave who was undergoing “correction,” it would not be considered a crime.

The Back-to-Africa Movement: also known as black Zionism or colonization movement was the the view that Americans of African ancestry should return to Africa. It failed woefully as most black Americans did not want to return to Africa. This is most likely because they didn't know the homelands of their ancestors and were not sure where to begin(afraid of starting afresh) or what the "strange land" of Africa held for them.

the Missouri compromise tried to achieve a balance of power between slave states and free states in Congress. It made Missouri a slave state and Maine a free state

The North was becoming more urban and industrial as there was the increase in population with new immigrants. The South started to lose its power in Congress.

John C. Calhoun was a South Carolina senator and was known to utilize the argument of states' rights to protect slavery in the Nullification Crisis of 1832-1833.

States' rights in American refers to the political powers that reserved only/exclusive to the U.S. state governments rather than the federal government as defined by the United States Constitution.

Secession: this is the act of withdrawing from a country or territory or state to form another government(country or territory). Advocates of secession are known as disunionists.

To avoid dissolution of the Union by appeasing both sides on the slavery issue. This is because the threat of dissolution was mainly founded on outstanding slavery issues and tension that would eventually bring about the civil war.

In Africa, folktales is the medium through which the historical events are passed to people and to the next generation.

  • Folktales refers to historical stories in the oral tradition that people tell other orally rather than in written form.
