Answer 1

Ответ: -1/10(17m+12)

Пошаговое объяснение:

Answer 2

-(11/2m-67/10)-(79/10-19/5m)=-1/10(55m-67)-1/10(79-38m)=-1/10(55m-67+79-38m)=-1/10(17m+12)=-0,1(17m+12)

Answer 3

To simplify the expression -(5,5m-6,7)-(7,9-3,8m), we can distribute the negative sign to each term within the parentheses.

First, let's distribute the negative sign to the first set of parentheses:

-(5,5m - 6,7) = -5,5m + 6,7

Now, let's distribute the negative sign to the second set of parentheses:

-(7,9 - 3,8m) = -7,9 + 3,8m

Therefore, the simplified expression becomes:

(-5,5m + 6,7) - (7,9 - 3,8m)

Now, we can simplify further by removing the parentheses:

-5,5m + 6,7 - 7,9 + 3,8m

Next, we can combine like terms:

(-5,5m + 3,8m) + (6,7 - 7,9)

Simplifying the coefficients of 'm':

(-5,5 + 3,8)m + (6,7 - 7,9)

-1,7m - 1,2

So, the simplified expression is -1,7m - 1,2.
