Question

Саша подарил Юле розы и орхидеи, причём орхидей было в 4 раза меньше, чем роз.Сколько роз С. подарил Ю., если известно, что роз было на 51 больше, чем орхидей?

Answer 1

обозначим орхидеи как х, тогда роз будет 4х (по усл орх меньше в 4 раза)

тогда 4х-х=51 (усл, что одних больше на 51) решаем ур-ие

3х=51

х=51/3

х=17 орхидей, тогда роз 17*4=68, 68-17=51 значит задача решена верно

Answer 2

орхидеи - х+51

розы - 4х

 

1) 4х=х+51

4х-х=51

3х=51

х=51:3

х= 17 - орхидей

2) 17*4= 68 - роз

Answer 3

Problem Analysis

We are given that Sasha gave Yulia roses and orchids as a gift. The number of orchids was four times less than the number of roses. Additionally, we know that there were 51 more roses than orchids. We need to determine how many roses Sasha gave Yulia.

Solution

Let's assume the number of orchids Sasha gave Yulia is x. According to the problem, the number of roses is 51 more than the number of orchids, so the number of roses is x + 51.

We are also given that the number of orchids is four times less than the number of roses. This means that x = (x + 51)/4.

To solve this equation, we can multiply both sides by 4 to eliminate the fraction:

4x = x + 51

Now, we can solve for x:

4x - x = 51

3x = 51

x = 51/3

x = 17

Therefore, Sasha gave Yulia 17 orchids and 17 + 51 = 68 roses.

Answer

Sasha gave Yulia 68 roses.

Explanation

Sasha gave Yulia 17 orchids and the number of roses was 51 more than the number of orchids. Therefore, the total number of roses Sasha gave Yulia is 17 + 51 = 68.
