Answer 1

Ответ:

1. (a+1,6)-(a+2,4)=a+1,6-a-2,4=1,6+2,4= - 0,8

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

3. -(x-2,7+y)-(6,5-x)= - x+2,7-y-6,5+x= - 3,8-y

Answer 3

Let's solve each equation step by step:

1. $(a+1.6) - (a + 2.4)$ $= a + 1.6 - a - 2.4$ $= -0.8$

2. $-(3.4 - x) + (-x + 1.6)$ $= -3.4 + x - x + 1.6$ $= -1.8$

3. $-(x - 2.7 + y) - (6.5 - x)$ $= -x + 2.7 - y - 6.5 + x$ $= -3.8 - y$

4. $-6 - a$ and $a + 17$ The two expressions are not connected, so we cannot simplify them further without additional information.

5. $a - b + c$ and $-a + b + c$ The two expressions cancel out each other: $(a - b + c) + (-a + b + c) = 0 + 0 + 2c = 2c$

6. $7.3 - 4.6 + 5.8$ and $-10.4 + 4.6 - 5.8$ $= 7.3 - 4.6 + 5.8 - 10.4 + 4.6 - 5.8$ $= -4.1$
