So the Correct answer would be all three of them.
This includes 27:18, 12:8, and 21:14.
The math behind this includes proportions.
For instance, if you multiple 3 by 9, you get 37. You have to multiple 2 by 9 now, and you should get 18. This is how all three of the answers are correct!

Answer:

All the above

Step-by-step explanation:

3:2 x 9 = 27:18      3:2 x 4 = 12:18    3:2 x 7 = 21:14

newspapers per pile

Answers

30 newspapers/2 piles = 15 newspapers/1 pile

It’s just reducing 30/2 into a fraction with a denominator of 1.

Answer:

15 newspapers

Step-by-step explanation:

30 newspapers spread over 2 piles is 30/2 = 15 newspapers

The question doesn't say spread but in language if it doesn't separate we can say the group word spread as it is most likely to be a group total of 30 spread over 2 piles.

find the exact coordinates of X on segment JK that is 1/3 the distance from j to k. J (-1,4)​ K(5,-3)

Answers

Answer:

(1, 5/3)

Step-by-step explanation:

the first coordinate of X would be -1 + (1/3 of 5 - (-1)) which is equivalent to -1 + (1/3 of 6) which is equal to -1 + 2 which is equal to 1. This is because the -1 is the first coordinate of J.

The second coordinate of X would be 4 - (1/3 of 4 - (-3)) which is equivalent to 4 - (1/3 of 7) which is equivalent to 4 - (7/3) = 12/3 - 7/3 = 5/3.

Therefore, the coordinate of X would be (1, 5/3) or (1, 1 2/3)

5 Answers: Choice A, B, C, D, E

Basically, it's everything except choice F.

=========================================================

Explanation:

The number 26 is a whole number since the set of whole numbers is {0,1,2,3,4,...} and it's also an integer as well because the set of integers includes the negative counterparts. That takes care of answer choices A and C.

The number 26 is rational because 26 = 26/1 which is a ratio or fraction of integers. Because it's rational, that means it cannot be irrational. The term "irrational" means "not rational". This means answer choice B is true while choice F is not true.

The number 26 is a natural number. The set of natural numbers is {1,2,3,4,...} which is effectively almost identical to the set of whole numbers, except 0 isn't involved. This is why choice D is another answer.

Lastly, choice E is an answer because 26 is a real number. Assuming you haven't learned about complex numbers yet, every number you encounter is a real number.

---------

So to summarize, the number 26 is...

a whole numbera rational numberan integera natural numbera real number

The only thing that it's not is irrational (which would contradict it being rational).
