Answer 1

Ответ:

1) -1,3

2) 5

3) -16

4) -2,4

5) 2,4

Answer 2

I'll solve each of these equations step by step:

1. $1.8 - 3.1$ $= -1.3$

2. $3.5 / 0.7$ $= 5$

3. $(-6.7) - (9.3)$ $= -16$

4. $-1.2 + 0.4 - 1.6$ $= -2.4$

5. $3.6 \times (-0.05)$ $= -0.18$

Now let's simplify the expression inside the second set of parentheses: $-3.2 - 0.8$ $= -4$

Substitute the value back into the main equation: $(-0.18) - (-4) \times 1.05$ $(-0.18) + 4.2$ $= 4.02$

So, the value of the expression $3.6 \times (-0.05) - (-3.2 - 0.8) \times 1.05$ is $4.02$. Unfortunately, I cannot interpret or provide images, but I hope this text-based solution helps!
