Question

К празднику купили красные и желтые шары.Всего 36 штук. Сколько было красных шаров, если их было в три раза больше, чем желтых?

Answer 1

пусть колличество желтых шаров - х, тогда количество красных шаров - 3х.

составим уравнение:

3х+х=36

4х=36

х=9

 

находим количество красных шаров:

х*3=27

ответ: 27 красных шаров

Answer 2

Пусть х-желтые
         y-красные 

 

х+y=36

3x=y

 

Тогда
х+3х=36

х=9

y=9*3=27

 

Answer 3

Problem Analysis

We are given that red and yellow balloons were purchased for a holiday celebration. The total number of balloons is 36, and the number of red balloons is three times the number of yellow balloons. We need to determine the number of red balloons.

Solution

Let's assume the number of yellow balloons is x. According to the given information, the number of red balloons is three times the number of yellow balloons, so the number of red balloons is 3x.

The total number of balloons is 36, so we can write the equation:

x + 3x = 36

Simplifying the equation:

4x = 36

Dividing both sides of the equation by 4:

x = 9

Therefore, the number of yellow balloons is 9, and the number of red balloons is three times that, which is:

3 * 9 = 27

So, there were 27 red balloons.

Answer

There were 27 red balloons if there were three times as many red balloons as yellow balloons.
