Question

4,6-9,3-(-8,2)-1,8+6,1+(-4,8) ; -19,8 -4,14+6,34-7,31+0,9-0,37; -29 +(-18)-(-64)-57+41

Answer 1

Ответ:

3; -24,38; 1

Пошаговое объяснение:

4,6-9,3-(-8,2)-1,8+6,1+(-4,8) = 4,6-9,3+8,2-1,8+6,1-4,8 = 18,9-15,9=3

-19,8 -4,14+6,34-7,31+0,9-0,37 = -31,62+7,24 = -24,38

-29 +(-18)-(-64)-57+41 = -29-18+64-57+41 = -104+105 = 1

Answer 2

Let's solve each expression step by step:

1. 4,6 - 9 + 3 - (-8,2) - 1 + 8 + 6,1 + (-4,8)

To simplify this, let's combine the like terms:

4.6 - 9 + 3 + 8.2 - 1 + 8 + 6.1 - 4.8

Now, add the numbers together:

4.6 - 9 + 3 + 8.2 - 1 + 8 + 6.1 - 4.8 = (4.6 + 8.2 + 8 + 6.1) - (9 + 1 + 4.8) = 27.9 - 14.8 = 13.1

So, the result is 13.1.

2. -19.8 - 4.14 + 6.34 - 7.31 + 0.9 - 0.37

Simply add the numbers together:

-19.8 - 4.14 + 6.34 - 7.31 + 0.9 - 0.37 = -25.04

So, the result is -25.04.

3. -29 + (-18) - (-64) - 57 + 41

First, simplify the double negative:

-29 + (-18) + 64 - 57 + 41

Now, add the numbers together:

-29 + (-18) + 64 - 57 + 41 = -29 + 64 - 18 - 57 + 41 = 1 - 18 - 57 + 41 = -17 - 57 + 41 = -16 - 57 = -73

So, the result is -73.

To summarize:

1. 4,6 - 9 + 3 - (-8,2) - 1 + 8 + 6,1 + (-4,8) = 13.1
2. -19,8 - 4,14 + 6,34 - 7,31 + 0,9 - 0,37 = -25,04
3. -29 + (-18) - (-64) - 57 + 41 = -73
