Question

В двух наборах 18 кубиков. Количество кубиков в одном наборе составляет половину кубиков в другом. Сколько кубиков в каждом наборе?

Answer 1

Х-кубиков в одном наборе. 2х- кубиков в другом наборе. 2х+х=18. 3х=18. х=18:3. х=6. -кубиков в одном наборе. 2*6=12 -кубиков в другом наборе.

Answer 2

Solution:

Let's solve this problem step by step.

1. Let's assume the number of cubes in the first set is x and the number of cubes in the second set is y.

2. According to the given information, the number of cubes in one set is half of the number of cubes in the other set. This can be represented as: - x = (1/2)y or y = 2x.

3. We also know that the total number of cubes in both sets is 18. This can be represented as: - x + y = 18.

4. Now, we can use the second equation to express y in terms of x and substitute it into the first equation to solve for x.

Substituting y = 18 - x into y = 2x: - 18 - x = 2x.

Solving for x: - 18 = 3x - x = 6.

5. Now that we have the value of x, we can find the value of y using the equation y = 18 - x: - y = 18 - 6 - y = 12.

Answer:

So, there are 6 cubes in one set and 12 cubes in the other set.
