Question

Ребят. Нужно решить задачи НЕ уравнением.а) С трёх полей собрали урожай картофеля. С первого поля собрали 3890 кг,а с третьего 9007 кг. Сколько килограммов картофеля собрали со второго поля,если с первого и второго полей вместе собрали на 1998 кг меньше,чем с третьего?б) На одной платформе поместили контейнер с картофелем массой 3890 кг и контейнер со свёклой неизвестной массы,а на другой платформе - трактор массой 9007 кг и сеялку массой 1998 кг. Чему равна масса контейнера со свёклой,если массы грузов на платформах равны?

Answer 1

Значит, с 3 поля собрали на 1998кг больше, чем с 1 и 2   Из 3 поля отнимай разницу                9007-1998=7009кг и сюда еще входит и первое поле, отнимай его...                7009кг-3890кг=3119кг собрали со второго поля...
Проверка: 9007-3890-3119=1998 кг (больше, как в условии.....
б)Находи известное...на второй платформе все известно. складывай  9007+1998=11005кг  теперь на первой платформе известен общий вес и вес картофеля, можно найти вес свеклы... 11005кг-3890кг=7115кг свеклы... Удачи!

Answer 2

Task a)

To solve this problem, we need to find the weight of the potatoes harvested from the second field. We are given the weights of the potatoes harvested from the first and third fields, and a relationship between the weights harvested from the first, second, and third fields.

Let's denote: - Weight of potatoes harvested from the first field as P1 (given as 3890 kg) - Weight of potatoes harvested from the third field as P3 (given as 9007 kg) - Weight of potatoes harvested from the second field as P2 (to be calculated)

We are also given that the combined weight of potatoes harvested from the first and second fields is 1998 kg less than the weight harvested from the third field. This can be expressed as an equation:

P1 + P2 = P3 - 1998

We can use this equation to find the weight of potatoes harvested from the second field.

Let's calculate P2 using the given values.

P2 = P3 - P1 + 1998

P2 = 9007 - 3890 + 1998

P2 = 7115 + 1998

P2 = 9113 kg

So, the weight of potatoes harvested from the second field is 9113 kg.

Task b)

In this task, we need to find the mass of the container with beets (swedes) based on the given masses of the containers with potatoes and beets, and the masses of the tractor and the seeder.

Let's denote: - Mass of the container with potatoes as M_potatoes (given as 3890 kg) - Mass of the container with beets as M_beets (to be calculated) - Mass of the tractor as M_tractor (given as 9007 kg) - Mass of the seeder as M_seeder (given as 1998 kg)

We are given that the total masses on both platforms are equal, which can be expressed as an equation:

M_potatoes + M_beets = M_tractor + M_seeder

We can use this equation to find the mass of the container with beets.

Let's calculate M_beets using the given values.

M_beets = M_tractor + M_seeder - M_potatoes

M_beets = 9007 + 1998 - 3890

M_beets = 11005 - 3890

M_beets = 7115 kg

So, the mass of the container with beets is 7115 kg.

I hope this helps! If you have further questions, feel free to ask.
