Question

1)-c-(b-c)2)-3n-(8m-3n)3)-5*(a+b)4)6,5-(-2,1+6,5)5)-(4-x)-(2x-6)​

Answer 1

Ответ:

1) -b

2) -8m

3) -5a-5b

4) 2,1

5) 2-x

Пошаговое объяснение:

1) -c-b+c=-b

2) -3n-8n+3n=-8m

3)-5a-5b

4)6,5-4,4=2,1

5)-4+x-2x+6=2-x

Answer 2

Let's simplify the expressions step by step:

1. -c - (b - c): Distribute the negative sign: -c - b + c

   Now, combine like terms (c and -c): -b

2. -3n - (8m - 3n): Distribute the negative sign: -3n - 8m + 3n

   Now, combine like terms (-3n and 3n): -8m

3. -5 * (a + b): Distribute the -5 to both terms inside the parentheses: -5a - 5b

4. 6,5 - (-2,1 + 6,5): Subtract the expression inside the parentheses from 6.5: 6.5 - (-2.1 + 6.5)

   Now, simplify the expression inside the parentheses: 6.5 - 4.4

   Subtract the result: 2.1

5. (4 - x) - (2x - 6): Distribute the negative sign: 4 - x - 2x + 6

   Combine like terms (4 and 6): 10 - x - 2x

   Combine like terms (-x and -2x): 10 - 3x

So, the simplified expressions are:

1. -b
2. -8m
3. -5a - 5b
4. 2.1
5. 10 - 3x
