Пошаговое объяснение:

50 s+ 55 s=1ч45мин

3һ – 5 min=2ч55мин

24 min • 8=3ч12мин

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction:

1. Perform operations inside parentheses/brackets first.
2. Next, perform any multiplication or division from left to right.
3. Finally, perform any addition or subtraction from left to right.

The expression is: 50s + 55s - (5min * 24min) • 8

1. Convert the units to the same format: 1 min = 60 s

2. Perform operations inside parentheses/brackets: 5min * 24min = 5 min * 24 min = 5 * 24 * 60 s * 60 s = 7200 s * 60 s = 432000 s^2

3. Now substitute the result back into the expression: 50s + 55s - 432000s^2 • 8

4. Perform multiplication:

• 432000s^2 * 8 = - 3456000s^2

5. Simplify the expression further: 50s + 55s - 3456000s^2

6. Combine like terms: (50 + 55) s - 3456000s^2 = 105s - 3456000s^2

So, the simplified expression is 105s - 3456000s^2.
