Question

(6,3a-0.8 b )+ (2,4b+ 1,7 a)-( 5,6-2,1a)

Answer 1

Ответ:

10,1a-1,6b-5,6

Пошаговое объяснение:

(6,3a-0,8 b )+ (2,4b+ 1,7 a)-( 5,6-2,1a)=

=6,3a-0,8b+2,4b+1,7a-5,6+2,1a=

=6,3a+1,7a+2,1a-0,8b+2,4b-5,6=

=10,1a-1,6b-5,6

вроде так

Answer 2

To perform the given arithmetic operation, let's combine the like terms:

(6,3a - 0.8b) + (2,4b + 1,7a) - (5,6 - 2,1a)

First, let's add the terms with 'a':

(3a + 1,7a) = 4,7a

Next, let's add the terms with 'b':

(-0.8b + 2,4b) = 1.6b

Now, we can combine the constant terms:

(6 + 5) = 11

Putting it all together:

(6,3a - 0.8b) + (2,4b + 1,7a) - (5,6 - 2,1a) = 4,7a + 1.6b + 11
