Eduardo had 16 more stamps than carson. 1/2 of carson's stamps were equal to 1/4 of eduardo's stamps.

MaRussiya [10]

Solution:
Part: 1
Let the number of stamps with Carson = x and Eduardo = y

So, equation as per given information:

y = x + 16 -- equation 1
1/2x = 1/4y --equation 2

Through equation 1, we get value of y as x+16

Putting this value of y in equation 2,
1/2x = 1/4 (x+16)

4x = 2(x+16)
4x = 2x+32

By solving, we get x = 16

So, Carson has 16 stamps. And, Eduardo has 16 stamps more than Carson which means Eduardo has 16+16 stamps which gives 32 stamps.

Carson = 16 stamps
Eduardo = 32 stamps.

Part: 2

After giving some stamps, Eduardo has 3/8 of Carson's stamp

3/8 of 16 stamps = 6 stamps

So Eduardo now has 6 stamps.

Initially Eduardo had 32 stamps and he now have 6 stamps. So, 32-6 = 26 stamps have been given by Eduardo.

Answer: Eduardo gave 26 stamps.

Based on the list of grievances, was the Revolutionary War justified?

valentinak56 [21]

Answer:

Until the end of the Seven Years' War in 1763, few colonists in British North America objected to their place in the British Empire. Colonists in British America reaped many benefits from the British imperial system and bore few costs for those benefits. Indeed, until the early 1760s, the British mostly left their American colonies alone. The Seven Years' War (known in the United States as the French and Indian War) changed everything. Although Britain eventually achieved victory over France and its allies, victory had come at great cost. A staggering war debt influenced many British policies over the next decade. Attempts to raise money by reforming colonial administration, enforcing tax laws, and placing troops in America led directly to conflict with colonists. By the mid-1770s, relations between Americans and the British administration had become strained and acrimonious

Prompt: What were four causes of the US entry into World War I? Give a brief description of each cause. Rank them from most impo

Svetllana [295]

Answer:

1. The Lusitania

2. The German invasion of Belgium

3. American loans

4. The reintroduction of unrestricted submarine warfare

1. The Lusitania

In early 1915, Germany introduced a policy of unrestricted submarine warfare in the Atlantic. This meant U-Boats were hunting and sinking merchant shipping without warning. The RMS Lusitania left New York on 1st May, 1915, bound for Liverpool. On 7th May it was spotted off the coast of Ireland by U-20 and torpedoed. Of 1,962 passengers, 1,198 lost their lives. Among the dead were 128 Americans, causing widespread outrage in the US.

2. The German invasion of Belgium

Following Germany’s invasion of neutral Belgium in 1914, stories began to circulate about atrocities committed against Belgian civilians. These stories, both true and exaggerated, were seized upon for propaganda. So-called “atrocity propaganda” spread far and wide, painting the Germans as a barbaric nation bent on ruthless, indiscriminate destruction. This propaganda was soon sweeping the US, firing anti-German sentiment.

3. American loans

The US had a vested financial interest in the outcome of the war in Europe. American businesses and banks made huge loans to the Allies. If they didn’t win then they were unlikely to get their money back.

4. The reintroduction of unrestricted submarine warfare

Germany resumed unrestricted submarine warfare in 1917. Knowing they risked provoking the United States into joining the war, Germany gambled on defeating the British before the US had a chance to mobilise. During February and March, several US cargo vessels were sunk without warning, resulting in the United States severing diplomatic ties with Berlin.
