Answer 1

х - количество букетов

(114+2х)/х=5

114+2х=5х

3х=114

х=38 (чел.)

Answer 2

(114+2х):х=5

114+2х=5х

114=3х

х=114:3

х=38 букетов , значит 38 человек в классе

Answer 3

Problem Analysis

We are given that each graduate of a school is to receive an identical bouquet of flowers. The school has purchased 114 carnations for this purpose. When 2 additional carnations are added to each bouquet, there are 5 flowers in each bouquet. We need to determine the number of graduates in the school.

Solution

Let's assume the number of graduates in the school is x.

We know that each bouquet initially contains 5 flowers, and after adding 2 additional carnations, each bouquet contains 5 + 2 = 7 flowers.

The total number of flowers in all the bouquets can be calculated by multiplying the number of bouquets by the number of flowers in each bouquet. Since each bouquet contains 7 flowers, the total number of flowers is 7x.

We are also given that the school has purchased 114 carnations. Therefore, the total number of flowers is also equal to 114.

Setting up the equation: 7x = 114

To solve for x, we divide both sides of the equation by 7: x = 114 / 7

Now we can calculate the number of graduates in the school.

Calculation

Let's calculate the number of graduates in the school using the equation x = 114 / 7.

x = 114 / 7 = 16.2857

Since we cannot have a fraction of a graduate, we round the number to the nearest whole number.

The number of graduates in the school is approximately 16.

Answer

There were approximately 16 graduates in the school.
