Answer 1

Ответ:

(90000-56000*8)2-(90000-3500-24600)

544000кг - 61900кг= 482100кг

Пошаговое объяснение:

сделаем все в килограмы так как тонна= 1000кг а центнер=100кг

а ответ будет: 482 тоны 1 центнер

Answer 2

To simplify the expression, let's perform the arithmetic operations step by step:

1. First, perform the operations inside the parentheses: (90т - 56ц * 8) * 2 - (90т - 35ц - 246ц)

   The term inside the first parentheses is: 90т - 56ц * 8. To simplify this, we perform the multiplication first: 56ц * 8 = 448ц. So, the term becomes: 90т - 448ц.

   The expression now becomes: (90т - 448ц) * 2 - (90т - 35ц - 246ц).

2. Next, distribute the factor of 2 into the first parentheses: 2 * (90т - 448ц) - (90т - 35ц - 246ц)

   Multiplying 2 with each term inside the parentheses: 2 * 90т = 180т 2 * 448ц = 896ц

   The expression now becomes: 180т - 896ц - (90т - 35ц - 246ц).

3. Now, perform the operations inside the second parentheses: 180т - 896ц - 90т + 35ц + 246ц

   Combine like terms (terms with the same variables and exponents): (180т - 90т) = 90т (-896ц + 35ц + 246ц) = -615ц

   The expression becomes: 90т - 615ц.

So, the simplified expression is: 90т - 615ц.
