Answer 2

Ответ:

-57

Пошаговое объяснение:

-2*1,9=-3,8

-3,8*(-5)=19

19*2,5=47,5

47,5*(-0,4)=-19

-19*3=-57

Answer 3

Let's simplify the expression step by step:

1. -2 * 1 = -2
2. 9 * (-5) = -45
3. 2.5 * (-0.4) = -1
4. -1 * 3 = -3

So, the simplified expression is:

-2 + (-45) + (-1) + (-3) = -2 - 45 - 1 - 3 = -51 - 4 = -55

Therefore, the answer is -55.
