Answer 2

Ответ:

1)-5+4.5+(-4.5)= -5

2)-0.5 +3.5+(-4.5)= -1,5

Answer 3

1. The expression -5 + 4.5 + (-4.5) can be simplified as follows:

-5 + 4.5 + (-4.5) = -5 + 4.5 - 4.5

Since -4.5 and +4.5 cancel each other out, the expression simplifies to:

-5 + 4.5 - 4.5 = -5

Therefore, the result is -5.

2. The expression -0.5 + 3.5 + (-4.5) can be simplified as follows:

-0.5 + 3.5 + (-4.5) = -0.5 + 3.5 - 4.5

Since -4.5 and +3.5 cancel each other out, the expression simplifies to:

-0.5 + 3.5 - 4.5 = -1.5

Therefore, the result is -1.5.
