A deli owner sold 90 sandwiches in one day. Of those sandwiches, 36 were pastrami. Write an equation to show what percent of sandwiches sold were pastrami
Answer:
36/90 * 100 = p
(p is percent sold that were pastrami)
Step-by-step explanation:
First, 36/90 (part over whole), simplifies to 40/100. We can multiply that by 100 to get a percentage. And that is your equation.

Read this excerpt from Immigrant Kids, by Russell Freedman.
Edward Corsi, who later became United States Commissioner of Immigration, was a ten-year-old Italian immigrant when he sailed into New York harbor in 1907:
My first impressions of the New World will always remain etched in my memory, particularly that hazy October morning when I first saw Ellis Island. The steamer Florida, fourteen days out of Naples, filled to capacity with 1600 natives of Italy, had weathered one of the worst storms in our captain's memory; and glad we were, both children and grown-ups, to leave the open sea and come at last through the Narrows into the Bay.
My mother, my stepfather, my brother Giuseppe, and my two sisters, Liberta and Helvetia, all of us together, happy that we had come through the storm safely, clustered on the foredeck for fear of separation and looked with wonder on this miraculous land of our dreams.
The purpose of this excerpt is to help readers understand
A) the excitement and relief immigrants felt upon arriving in America.
B) that the Narrows into the Bay was a very dangerous passage.
C) that Italian children were very sad after leaving their home country.
D) the weather the immigrants experienced on that day in October 1907.

о G Kelly opened a bank account that earns 1.2% simple interest each year. After 7 years, Kelly will earn $126 in interest. How much did Kelly deposit when she opened the account?
Answer:
$1,512
Step-by-step explanation:
1.2% of $126 = $1,512
I really dont l know if this is right but I think it is
Answer:
$15
Step-by-step explanation:
Interest=principle X interest rate X the time(In this case years)
So, $126= p X 1.2% X 7
We first multiply 1.2% by 7 and get .084, then we move the decimal to places to the right and get 8.4.After that we divide $126 by 8.4 and you should get 15.So thats how I got $15 but then again I may be wrong.Hope this works for you =)
Gray read his book on 3 different weeks. On week 1 gray read 234 pages of the book. On week 2 gray readthe same number of pages on week 1. On week 3, he read 100 pages less than he read on week 2. What was the total number of pagesless than he read on week 2
Answer:
602 pages
Step-by-step explanation:
Given that he read his book on 3 different weeks in the manner;
week 1 - 234 pages
week 2 - 234 pages
week 3 - 100 pages less than he read on week 2
This means that the number of pages read on week 3
= 234 - 100
= 134 pages
Hence the total number pages in the book
= 234 + 234 + 134
= 602 pages
Answer:602

-7 - 12 = - 7х + 3(-4 - x)
Answer: x = -1.8
Step-by-step explanation:
-7 - 12 = -7x + 3 (-4 - x)
-7x + 3 (-4 - x) = -7 - 12
P.S I switched the order cuz I find it easier to solve this way.
-7x + 3 (-4 - x) = -7 - 12
Distribute
-7x - 12 - 3x = - 7 + 13
Add 12 to both sides
-7x - 3x = -7 + 13 + 12
Combine like terms
-10x = 18
Divide both sides by -10
x = -1.8

Write2.1 as a mixed number and as an improper fraction.
Do not try to simplify your answers.
Answer:
2 1/10 and 21/10
Step-by-step explanation:
2.1 is 2 + 0.1 when expanded.
2 is just 2 and then 0.1 as a fraction is 1/10. The mixed number would be 2 1/10.
The improper fraction is just 21/10 (convert the mixed number into improper form).
Converting from mixed number to improper: Multiply the number in the front (in this case 2) by the denominator.
That is 2 x 10 which is 20. Then add that number (20) to the numerator. 20 + 1 is equal to 21.
21 would be our numerator and the denominator would stay the same (10).
21/10 is the improper form.
