In a class, 22 students have been on a plane, 28 on a train, 23 on a boat, 15 on a plane and train, 20 on a train and boat, 14 on a plane and boat, 12 on all three, and 1 on none of them. How many students are in the class?

Answers

Answer 1
Answer:

Answer:

37 students are in the class

Step-by-step explanation:

There are 8 regions which the most inclusive clue is the inner one with 12.

  • "14 on a plane and boat" so we fill the intersection with plane and boat with 14-12=2
  • "20 on train an boat" 20-12=8 in the intersection
  • "15 on plane and train" = 15-12 = 3

now we look at this:

  • "22 students have been on a plane" 22 - (2+12+3) = 5 on the plane
  • "28 on a train" 28 - (12+8+3) = 5 on the train
  • "23 on a boat" 23-(12+8+2) = 1 on the boat

Just add up all the 8 numbers in the regions:

12+2+8+3+5+5+1+1=37

Use an inequality symbol (<, >, =, ≤) to compare −3 + 7 _____ −10 − 2 A. > B. < C. = D. ≤

Answers

By using the concept of inequality, the solution for the correct inequality used between the given numbers is,

(- 3 + 7 ) > (- 10 - 2)

Used the concept of inequality, which states that,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that,

Compare the numbers (- 3 + 7) and ( - 10 - 2).

Now, to compare the numbers we can solve each side,

(- 3 + 7) = - 3 + 7

= 7 - 3

= 4

(- 10 - 2) = - 10 - 2

= - 12

So, by the definition of positive and negative numbers, we get,

4 > - 12

As positive numbers are always greater than negative numbers.
