Question

Ребята из московской школы провели товарищеские игры со школьниками Чикаго 7 В нью-йорке 5 В Бостоне в четырех школах всего было 48 встреч сколько встреч было проведено между московскими и американскими школьниками если в каждой американской школе было проведено равное число встреч

Answer 1

1) 7+5+4=16 (школ) - всего посетили
2) 48:16=3 (встречи) - в одной школе
3) 7*3=21 (встречи) - в Чикаго
4) 5*3=15 (встреч) - в Нью-Йорке
5) 4*3=15 (встреч) - в Бостоне

Answer 2

Calculating the Number of Meetings Between Moscow and American Schoolchildren

To calculate the number of meetings between Moscow and American schoolchildren, we can use the information provided in the question.

Given: - Moscow schoolchildren had friendly games with schoolchildren from Chicago 7 times, New York 5 times, and Boston an unspecified number of times. - In total, there were 48 meetings in four schools.

Let's denote the number of meetings in Boston as B.

The total number of meetings can be expressed as the sum of the meetings in Chicago, New York, Boston, and Moscow, which equals 48:

7 (Chicago) + 5 (New York) + B (Boston) + Moscow = 48

Since the question states that there were an equal number of meetings in each American school, we can assume that the number of meetings in Chicago and New York is the same. Therefore, the number of meetings in Chicago and New York can be represented as C.

The equation can be rewritten as:

C + C + B + Moscow = 48

Since C + C equals 2C, the equation becomes:

2C + B + Moscow = 48

Solving for the Number of Meetings

To solve for the number of meetings between Moscow and American schoolchildren, we need to find the values of C and B.

Given that C + C equals 2C, and the total number of meetings is 48, we can solve for C and B using the information provided.

Let's denote the number of meetings between Moscow and American schoolchildren as M.

We can express the total number of meetings as:

2C + B + M = 48

Since the number of meetings in Chicago and New York is the same, we can denote it as C.

Calculating the Number of Meetings in Each American School

To find the number of meetings in each American school, we can use the fact that the number of meetings in Chicago and New York is the same. Therefore, the number of meetings in each American school is:

C = (7 (Chicago) + 5 (New York)) / 2

Calculating the Number of Meetings Between Moscow and American Schoolchildren

Now, we can use the calculated value of C to find the number of meetings between Moscow and American schoolchildren:

M = 48 - 2C - B

Substitute the value of C to find M.

Conclusion

By following these steps, we can calculate the number of meetings between Moscow and American schoolchildren based on the given information.
