Answer 1

1)х-28=58+37
2)8х=80•12
3)х:28=300-203

Answer 2

Task 1: Какое число надо уменьшить на 28 чтобы получить число, равное сумме чисел 58 и 37?

To solve this task, we need to find the number that, when decreased by 28, will be equal to the sum of 58 and 37.

Let's denote the unknown number as 'x'. According to the problem, we have the equation:

x - 28 = 58 + 37

To find the value of 'x', we can simplify the equation:

x - 28 = 95

Now, we can solve for 'x' by adding 28 to both sides of the equation:

x = 95 + 28

Simplifying further, we get:

x = 123

Therefore, the number that needs to be decreased by 28 to obtain a number equal to the sum of 58 and 37 is 123.

Task 2: Какое число надо увеличить в 8 раз чтобы получить число, равное произведению чисел 80 и 12?

To solve this task, we need to find the number that, when multiplied by 8, will be equal to the product of 80 and 12.

Let's denote the unknown number as 'x'. According to the problem, we have the equation:

8x = 80 * 12

To find the value of 'x', we can simplify the equation:

8x = 960

Now, we can solve for 'x' by dividing both sides of the equation by 8:

x = 960 / 8

Simplifying further, we get:

x = 120

Therefore, the number that needs to be increased by 8 times to obtain a number equal to the product of 80 and 12 is 120.

Task 3: Какое число надо уменьшить в 28 раз чтобы получить число, равное разности чисел 300 и 203?

To solve this task, we need to find the number that, when decreased by 28 times, will be equal to the difference between 300 and 203.

Let's denote the unknown number as 'x'. According to the problem, we have the equation:

x / 28 = 300 - 203

To find the value of 'x', we can simplify the equation:

x / 28 = 97

Now, we can solve for 'x' by multiplying both sides of the equation by 28:

x = 97 * 28

Simplifying further, we get:

x = 2716

Therefore, the number that needs to be decreased by 28 times to obtain a number equal to the difference between 300 and 203 is 2716.
