Question

Решите задачу? Для праздничной иллюминации улицы было использованно в 3 раза меньше красных лампочек ,чем жёлтых.Сколько лампочек каждого цвета?Всего 803 лампочек.

Answer 1

Пусть использовали х - красных лампочек, тогда жёлтых - 3*х, и зелёных - 3+х
всего 803 или х+3*х+3+х
отсюда получаем 2х+3х+3=803     5х=800    х=160 -красных
480-жёлтых и зелёных - 163

Answer 2

Problem Analysis

We are given that the number of red light bulbs used for the holiday illumination is three times less than the number of yellow light bulbs. We need to determine the number of light bulbs of each color, given that there are a total of 803 light bulbs.

Solution

Let's assume the number of yellow light bulbs is represented by x. According to the problem statement, the number of red light bulbs is three times less than the number of yellow light bulbs, which means the number of red light bulbs is x - 3x = -2x.

We can set up the following equation to represent the total number of light bulbs: x + (-2x) = 803

Simplifying the equation, we have: -x = 803

To solve for x, we can multiply both sides of the equation by -1: x = -803

However, since the number of light bulbs cannot be negative, we can conclude that there is no solution to this problem.

Therefore, it is not possible to determine the number of light bulbs of each color given the information provided.

Conclusion

Based on the given information, it is not possible to determine the number of red and yellow light bulbs used for the holiday illumination. The problem does not have a valid solution.
