Question

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

Answer 1

Ответ:

Пошаговое объяснение:

-6,4*0,3+5,4*0,3=0.3(-6.4+5.4)=0.3*(-1)=-0.3

-0.3:(-0.2)=-1.5

-1.5-5.1=-6.6

Answer 2

Let's break down the expression step by step:

(-6,40,3+5,40,3):(-0,2) - 5,1

First, let's perform the multiplication and addition within the parentheses:

(-6.4 * 0.3 + 5.4 * 0.3) : (-0.2) - 5.1

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

= -0.3 : (-0.2) - 5.1

Now, let's calculate the division:

-0.3 : (-0.2) = 1.5

Substituting the result back into the expression:

1.5 - 5.1

Finally, let's subtract:

1.5 - 5.1 = -3.6

Therefore, the result of the expression is -3.6.
