Question

Решение задач, Кофейник и две чашки вмещают 740 г воды . В кофейник входит на 380 г воды больше, чем в чашку . Сколько граммов воды вмещает кофейник

Answer 1

Пусть в чашку вмещается x граммов, тогда в кофейник входит (x+380) граммов. В кофейник и две чашки входит (x+x+(x+380)), что по условию задачи равно 740 г.

                            Можем составить и решить ур-ние

x+x+x+380= 740
3x=740-380
3x=360
x=120 2) 120+380=500(г) Ответ: 500 грамм

Answer 2

Problem Analysis

We are given that a coffee pot and two cups together can hold 740 grams of water. The coffee pot can hold 380 grams more water than one cup. We need to determine the capacity of the coffee pot.

Solution

Let's assume the capacity of one cup is x grams. According to the problem, the coffee pot can hold 380 grams more water than one cup. Therefore, the capacity of the coffee pot is x + 380 grams.

The total capacity of the coffee pot and two cups is given as 740 grams. We can set up the following equation to solve for x:

x + (x + 380) + x = 740

Simplifying the equation:

3x + 380 = 740

Subtracting 380 from both sides:

3x = 360

Dividing both sides by 3:

x = 120

Therefore, the capacity of one cup is 120 grams.

To find the capacity of the coffee pot, we can substitute the value of x into the expression x + 380:

120 + 380 = 500

Therefore, the coffee pot can hold 500 grams of water.

Answer

The coffee pot can hold 500 grams of water.
