Question

Мумин-мама поставила в вазы ромашки васильки. В одну вазу она поставила 5 цветов, во вторую -в 3 раза больше, а в третью- на 8 меньше, чем во вторую. во всех вазах оказалась 9 ромашек. Сколько василька было в вазах?

Answer 1

1-я ваза: 5 цв.
2-я ваза: 5 цв. * 3 = 15 цв.
3-я ваза: 15 цв. - 8 цв. = 7 цв.
Всего: 5 + 15 + 7 = 27 (цв.)
Ромашки = 9 цв.
Васильки = 27 - 9 = 18 (цв.)

Answer 2

В 1-вазе -5цветов, во2-вазе- 5*3=15, в 3-ей вазе-15-8=7цветов. Итого получается 5+15+7=27цветов. Из 27 цветов 9 ромашек, значит остальные 27-9=18 васильки

Answer 3

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the number of violets in each vase.

Let's denote: - x as the number of chamomiles in the first vase, - y as the number of chamomiles in the second vase, and - z as the number of chamomiles in the third vase.

Given: 1. In the first vase, there are 5 chamomiles. 2. In the second vase, there are 3 times more chamomiles than in the first vase. 3. In the third vase, there are 8 less chamomiles than in the second vase. 4. In total, there are 9 chamomiles in all vases.

We can represent this information as a system of equations: 1. x + y + z = 9 (total number of chamomiles) 2. x = 5 3. y = 3x 4. z = y - 8

Now, let's solve the system of equations to find the number of chamomiles in each vase.

First, we substitute the value of x into equations 3 and 4: - y = 3*5 = 15 - z = 15 - 8 = 7

So, the number of chamomiles in each vase is: - First vase: 5 chamomiles - Second vase: 15 chamomiles - Third vase: 7 chamomiles

Answer:

Therefore, there were 15 violets in the vases.
