How did Galileo's ideas change the way Europeans looked at the universe?
(One paragraph long)

Answers

People thought that the earth was the center of the universe and everything revolved around it, but people like Galileo disproved this and changed the way people understood the universe and were the ones to say the earth revolves around the sun. He also showed the planets revolve around the sun-or a new way of thinking. But when Galileo was trying to make people see the universe a different way Galileo has now finally discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Galileo confirmed Copernicus's theories on the universe by noting that the Earth did indeed revolve around the Sun and not the other way around as was thought at the time. With this, he opposed the church dogma at the time.

4. Combine the two equations to eliminate one of the variables, and then solve for the other. (3 points: 1 for eliminating one variable, 1 for the answer, and 1 for showing your work)

5. Solve for the other variable. (2 points: 1 point for the answer, 1 for showing the work)

6. Prove that your solutions are correct by substituting the values back into the original equations and verifying the answers. (2 points)

I will answer 3,4,5 and 6 all together.

Enable to answer the question we need to follow the system of equations:

12x+6y=120 and 4x+y=30.

So now that we know our solutions we need to multiply the second equation by -3.

12x+6y=120 and -12x-3y=-90

Now we add both equations

12x- 12x + 6y- 3y= 120-90

3y=-30

y=10

This time let's find the value of "x"

4x+y= 304x+ 10= 30

4x=30-10

x= 20/4

X=5

Now that we have both values of x and y (5,10) we should make sure it's correct.

12(5)+6(10)=120

60+60=120

120=120

And

4(5)+10=30

20+10=30

30=30

Now that it's verified our final answer is (5,10).

Give one example of discrimination in the armed services during WWII?​

Answers

Before World War II (1939–1945) began, many African-Americans lived in the South. They eked out a living as tenant farmers or sharecroppers. As the nation prepared for war, better paying factory and manufacturing jobs became available in the North and on the coasts. Those opportunities encouraged many African-American men and women to relocate. Black Americans also moved to southern cities, such as Birmingham and Mobile, which grew into important military manufacturing centers. Those shifts from one part of the country to other parts led to other changes. People from different backgrounds came in contact with and worked with one another. Those experiences made black Americans determined to resist racial discrimination.
Although the U.S. government denounced Nazi racism overseas, white Americans maintained their own racist system of inequality and violence against black citizens. In many parts of the country, African-Americans were denied the right to vote. They attended segregated and inferior

schools. They faced discrimination or exclusion from branches of the military and certain jobs. And for some black workers, high unemployment and low wages remained.
The contradiction angered African-Americans. They demanded that the nation live up to its highest ideals. The Pittsburgh Courier, a black weekly newspaper, launched a "Double V" campaign in 1942. It called for "victory over our enemies from without" — the Germans and the Japanese — and "victory over our enemies from within" — American racism. Black Americans took those words seriously. They strongly supported the war effort and they also engaged in protests against racial injustice at home.
A. Philip Randolph led the way. He was the president of the Brotherhood of Sleeping Car Porters, a black labor organization. For decades, Randolph had challenged racial inequality. In September 1940, Randolph was part of a delegation that met with President Franklin D. Roosevelt and demanded that the president end segregation in the armed forces. Roosevelt did not act.
In January 1941, Randolph decided to take a more forceful approach. He proposed a m
