Determine if the expressions 100 divided by (25 divided by 5) and (100 divided by 25) divided by 5 are equivalent. If so, tell what property is applied. If not explain why.

Answers

Answer:

They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.  

Step-by-step explanation:

100/(5)=20    (4)/5= .8

The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

Expression 1:
100 ÷ (25 ÷ 5)

Evaluate the expression inside the parentheses.

25 ÷ 5 = 5

Replace the expression inside the parentheses with its result:

100 ÷ 5

Perform the division:

100 ÷ 5 = 20

So, the result of Expression 1 is 20.

Expression 2:
(100 ÷ 25) ÷ 5

Evaluate the expression inside the first set of parentheses.

100 ÷ 25 = 4

Replace the expression inside the first set of parentheses with its result:

4 ÷ 5

Perform the division:

4 ÷ 5 = 0.8

So, the result of Expression 2 is 0.8.

Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.

Harriet was born a slave in a plantation in Dorchester County, Maryland, where she was mistreated and abused with violence that caused permanent injuries. At age twenty, Harriet Tubman escaped at night guided by the North star and traveled many miles all the way to Pennsylvania, where slavery was illegal. Harriet Tubman then served as the "conductor" for the underground railroad. The Underground Railroad was a network of secret routes and safe houses established in the US which was used by African-American slaves. This network was used to help many African-American slaves escape safely. Harriet helped many slaves escape for eleven years, going back to Maryland risking her own freedom. In 1850, the Fugitive Slave Law was passed in the US which stated that escaped slaves could be captured in the North and returned to slavery, thus Harriet changed the routes to go to Canada.
