Olivia ordered 5 books online. Each book weighed 2 1/3 pounds. What is the total weight of Olivia's books if all the books are shipped to Olivia together?
Answers
How to solve:
*Turn 2 1/3 into an improper fraction by doing denominator x whole number + numerator, so 3 x 2 + 1 which is 7/3.
* Multiply both fractions by doing numerator x numerator and denominator x denominator.
*This gives you 35/3 and now you just simplify by seeing how much times 3 can go into 35 so it is 11 times and 2 left over, so it is 11 2/3
5 × 7/3 = 35/3
35/3 = 11 2/3 pounds
I hope this helped you :)

First, we need to convert the percentage (35%) into a decimal. We can do this by dividing the percentage over 100.
35/100 = 0.35
Now, our next step is to find 0.35% of $8.40 (original price of the novel). To do this, you need to multiply the percentage by the original price.
0.35% × $8.40 = 2.94
What we recently received (2.94), is the amount of money that we are saving from the sale. The original price of the novel was $8.40, and with the 35% off, we are saving $2.94 on it.
Our last step is to subtract the original price and the sale.
$8.40 - $2.94 = $5.46
Now - we know that our new cost just for the novel is $5.46.
------
Moving on to the bookmark which costs $1.20, we can start by taking our percentage from last time (0.35) and instantly start multiplying just like we did on the novel.
0.35% × $1.20 = $0.42
So, with the 35% discount, you are saving $0.42 on the bookmark. Let's subtract and find the total amount Edward is having to pay now.
$1.20 - $0.42 = $0.78
He will purchase the bookmark for only $0.78.
-----------
Our final step is to add both the novel and bookmark up to find the total price overall.
$5.46 + $0.78 = $6.24
Edward will have to pay $6.24 for both the novel and bookmark.

Answer:
Option A and C is correct.
Step-by-step explanation:
Discount is defined as a reduced price on something being sold or at a price lower than that item is normally sold for.
For a 20% discount,
Given:
Initial prices = $ d
Discounted price = % discount × original/initial cost
= 20/100 × d
= 0.2 × d
Selling price = original cost - discounted price
= d - 0.2d
= 0.8 × d
= 0.8d

one way would be to multply it out or set it equal to 11x where x is a whole number (if x is not a whole number, then it is not divisible)
11x=7^6+7^5-7^4
undistribute 7^4
11x=(7^4)(7^2+7^1-1)
11x=(7^4)(49+7-1)
11x=(7^4)(55)
56=5*11
11x=(7^4)(5)(11)
divide by 11
x=5(7^4)
aka, find if 11 is a factor of that number
x=5(7^4)
7^3(7^3 + 7^2 -7) = 7^3(385) = 7^3(35)(11) = 7^3(7)(5)(11) = 7^4(5)(11) :)))
