Пошаговое объяснение:

(20-22,05÷2,1)×6,4+9,2=70

1) 22,05÷2,1=10,5;

2) 20-10,5=9,5;

3) 9,5×6,4=60,8;

4) 60,8+9,2=70

Answer 2

To calculate the given expression, follow these steps:

1. Evaluate the expression inside the parentheses: (20-22,05: 2,1) First, perform the division: 22.05 ÷ 2.1 ≈ 10.5 Next, subtract 20 from the result: 10.5 - 20 ≈ -9.5

2. Now add the result from step 1 to the expression outside the parentheses: -9.5 + 6.4 + 9.2

3. Finally, perform the addition: -9.5 + 6.4 + 9.2 ≈ 5.1

So, the value of the expression is approximately 5.1.
