Question

В вазе лежат фрукты:груши,яблоки и мандарины.Мандаринов на12 штук больше,чем яблок,а груш на 3меньше,чем яблок.Сколько всего фруктов в вазе?

Answer 1

Пусть груши=х , тогда яблоки=х+3, мандарины х+3+12
составим уравнение
 1)х+х+3+х+3+12
 3х+3+3+12
 3х=18
 х=18:3
 х=6 

2)6+(6+3)+(6+3+12)
6+9+21=36 фруктов всего
ответ: в вазе всего 36 фруктов

Answer 2

Problem Analysis

We are given that there are pears, apples, and mandarins in a vase. The number of mandarins is 12 more than the number of apples, and the number of pears is 3 less than the number of apples. We need to determine the total number of fruits in the vase.

Solution

Let's assume the number of apples is x.

According to the given information: - The number of mandarins is 12 more than the number of apples, so the number of mandarins is x + 12. - The number of pears is 3 less than the number of apples, so the number of pears is x - 3.

To find the total number of fruits in the vase, we need to add the number of apples, pears, and mandarins together.

Calculation

The total number of fruits in the vase is:

Total = Apples + Pears + Mandarins

Total = x + (x - 3) + (x + 12)

Simplifying the equation:

Total = 3x + 9

Answer

Therefore, the total number of fruits in the vase is 3x + 9.

Please note that we don't have the value of x (the number of apples) in the given information, so we cannot determine the exact total number of fruits in the vase without that information.
