Question

6,4*0,3+5,4*0,3):(-0,2) - 5,1

Answer 1

6,4*0,3+5,4*0,3):(-0,2) - 5,1=(1.92+1.62)/(-0.2)-5.1=3.54/(-0.2)-5.1=-17.7-5.1=-22.8

Answer 2

Ответ:

(6,4*0,3+5,4*0,3):(-0,2) - 5,1

(1.92+1.62):(-0.2)-5.1

3.54:(-0.2)-5.1

-17.7-5.1

-22.8

Ответ:-22.8

Answer 3

Let's break down the given expression step by step:

1. Calculate the products inside each set of parentheses:

   • $6.4 \times 0.3 = 1.92$
   • $5.4 \times 0.3 = 1.62$

2. Add the products: $1.92 + 1.62 = 3.54$

3. Divide the sum by $-0.2$: $\frac{3.54}{-0.2} = -17.7$

4. Finally, subtract $5.1$: $-17.7 - 5.1 = -22.8$

So, the result of the given expression is $-22.8$.
