Question

8. ( 2 бали) Один комбайнер намолотив 4200 ц зерна, другий - на х ц більше, ніж перший. Скільки центнерів намолотили обидва комбайнери разом? Скласти вираз для розв'язування задачі і обчислити його значення, якщо х=457​

Answer 1

Ответ:

2=4200+х

х=457

2=4200+457=4657

Разом=4200+4657=8857

Answer 2

To solve this problem, we need to determine the total amount of grain harvested by both combine harvesters together. Let's break down the information given:

- The first combine harvester harvested 4200 centners of grain. - The second combine harvester harvested x centners more than the first one.

To find the total amount of grain harvested by both combine harvesters, we need to add the amount harvested by the first combine harvester to the amount harvested by the second combine harvester.

Let's denote the amount harvested by the second combine harvester as y centners. According to the information given, y is x centners more than 4200 centners.

Therefore, the total amount of grain harvested by both combine harvesters is 4200 centners (from the first combine harvester) plus y centners (from the second combine harvester).

To find the value of y, we need to substitute the value of x into the equation. According to the problem, x is equal to 457.

Now, let's calculate the total amount of grain harvested by both combine harvesters:

Calculation:

- The first combine harvester harvested 4200 centners. - The second combine harvester harvested x centners more than the first one, which is 457 centners more.

So, the total amount of grain harvested by both combine harvesters is 4200 + (4200 + 457) centners.

Let's calculate the value:

4200 + (4200 + 457) = 4200 + 4657 = 8857 centners.

Therefore, both combine harvesters together harvested 8857 centners of grain.
