6)436 800

Answer 3

Let's solve each of these mathematical expressions step by step:

1. 800 - (540 ÷ 9) × 7 First, divide 540 by 9: 540 ÷ 9 = 60 Then, multiply 60 by 7: 60 × 7 = 420 Finally, subtract 420 from 800: 800 - 420 = 380

2. 100 - (400 ÷ 8) × 9 First, divide 400 by 8: 400 ÷ 8 = 50 Then, multiply 50 by 9: 50 × 9 = 450 Finally, subtract 450 from 100: 100 - 450 = -350

3. 6т 47кг - 3т 400кг To subtract these weights, convert them to the same unit. Since 1 тон (tonne) is equal to 1000 кг (kilograms), we can convert both weights to kilograms: 6т = 6 * 1000кг = 6000кг 3т 400кг = 3 * 1000кг + 400кг = 3400кг Now, subtract 3400кг from 6000кг: 6000кг - 3400кг = 2600кг

4. 42000 - 2706 × 4 + 17897 First, multiply 2706 by 4: 2706 × 4 = 10824 Then, subtract 10824 from 42000: 42000 - 10824 = 31176 Finally, add 17897 to 31176: 31176 + 17897 = 49073

5. 28936 × 4 Multiply 28936 by 4: 28936 × 4 = 115744

6. 72800 × 6 Multiply 72800 by 6: 72800 × 6 = 436800

So, the results are:

1. 380
2. -350
3. 2600кг
4. 49073
5. 115744
6. 436800
