Question

ДОМАШНЕЕ ЗАДАНИЕ Реши задачу. 8 Для подкормки животных в зоопарке одна 7 10 тонны овощей другая – на 300 кг овощей меньше. Сколько килограммов овощей было собрано? ​

Answer 1

Если так, как я понял то вот:

9 700

Решение:

10 тонн это 10 000 кг.

10 000 - 300 = 9 700 (кг.)

Answer 2

Problem Analysis

To solve this problem, we need to find the total weight of vegetables collected in the zoo. We are given that one batch of vegetables weighs 7 tons and another batch weighs 300 kg less than the first batch.

Solution

Let's denote the weight of the first batch of vegetables as x tons. According to the problem, the weight of the second batch is 300 kg less than the first batch. Since 1 ton is equal to 1000 kg, we can write the weight of the second batch as (x - 0.3) tons.

To find the total weight of vegetables collected, we need to add the weights of both batches. Therefore, the equation becomes:

x + (x - 0.3) = 10

Simplifying the equation, we have:

2x - 0.3 = 10

Now, we can solve this equation to find the value of x.

Calculation

Let's solve the equation:

2x - 0.3 = 10

Adding 0.3 to both sides:

2x = 10.3

Dividing both sides by 2:

x = 5.15

Answer

The weight of the first batch of vegetables is 5.15 tons. Since the second batch weighs 300 kg less than the first batch, the weight of the second batch is (5.15 - 0.3) = 4.85 tons.

Therefore, the total weight of vegetables collected is 5.15 + 4.85 = 10 tons.

So, a total of 10 tons of vegetables were collected in the zoo.

Verification

Let's verify our answer using the given information. We were given that one batch of vegetables weighs 7 tons and the other batch weighs 300 kg less.

If we subtract 300 kg (0.3 tons) from 7 tons, we get 6.7 tons.

Adding 6.7 tons to 3.3 tons (which is 300 kg less than 7 tons), we get a total of 10 tons.

Our answer of 10 tons is consistent with the given information, so we can be confident in our solution.

Conclusion

The total weight of vegetables collected in the zoo is 10 tons.
