Answer: 43. A) I think its 2 pairs of shoe and one shoe is left because the guy either lost it, or just has an extra shoe. 43. B) If one of the pairs is missing a shoe then there is 4 shoes because there was already one shoe missing a pair but it's still there so if one pair is missing one completely like, it's not there then there's five. 44. 4xy²+3x-5. 45. I am not good at this. But I think: Sally has x beans she gave 8 to Marcus. How many does Sally have now? 46. Yes because whatever y is times one is still going to be y and according to pemdas its multiplication the addition so therefore it would me 1xy then it would be yx4 and it would still be the same answer.

Which is bigger 2/3 or 7/8??

Answers

When you're comparing fractions, the best thing to do is to either find a common denominator or convert them into fractions. The lowest common denominator between 3 and 8 is 24. 
You've then got to multiply the first fraction by 8, giving you 16/24
You then multiply the second fraction by 3, giving you 21/24
You can also convert them into decimals.
2/3 as a decimal is 0.6666 (recurring)
7/8 as a decimal is 0.875

Therefore, 7/8 is bigger.
Hope this helps :) 

After setting up the denominator same, the fraction 7/8 is bigger than 2/3.

We have,

To determine which fraction is bigger between 2/3 and 7/8, we can compare them by finding a commondenominator and then comparing the numerators.

The commondenominator for 3 and 8 is 24.

To convert 2/3 and 7/8 to have the same denominator, multiply the numerator and denominator of 2/3 by 8 and the numerator and denominator of 7/8 by 3:

2/3 * 8/8 = 16/24

7/8 * 3/3 = 21/24

Now we can see that 16/24 is smallerthan 21/24.

Therefore,

7/8 is bigger than 2/3.

We know that they have:
2 entrences
3 ways to chose (escalator,elevator and stairs)
8 gates
and again 3 ways to chose (escalator, elevator and stairway)

now you have to multiply it:
2*3*8*3=6*8*3=48*3=144

Thirty copies of a textbook weigh a total of 75 lb. What is the weigh of each book?​

Answers

Answer: Each book weighs 2.5 pounds.

Step-by-step explanation: 75 divided by 2.5 is 30.  Or you could also get the answer by multiplying 30 and 2.5 which it would be 75. So, therefor, the answer is 2.5.

Final answer:

To find the weight of each textbook, we divide the total weight by the number of books. Therefore, each book weighs 2.5 lb.

Explanation:

If thirty copies of a textbook weigh a total of 75 lb, to find the weight of each individual book, we need divide the total weight by the number of books.

Here is a step-by-step explanation of the solution:

  1. Determine the total weight of the textbooks, which is 75 lb.
  2. Determine the number of books, which is 30.
  3. Divide the total weight by the number of books. So, 75 lb ÷ 30 = 2.5 lb.

Therefore, each book weighs 2.5 lb.
