Question

0,2(7а-6b)-0,3(3a-4b)

Answer 1

1,4а-1,2в-0,9а+1,2в=0,5а

Answer 2

1,4а-1,2b -0,9a +1,2 b = 0,5 a 

Answer 3

To simplify the expression 0.2(7a - 6b) - 0.3(3a - 4b), we can distribute the coefficients and simplify the terms:

0.2(7a - 6b) - 0.3(3a - 4b)

= 0.2 * 7a - 0.2 * 6b - 0.3 * 3a + 0.3 * 4b

= 1.4a - 1.2b - 0.9a + 1.2b

Now, let's combine like terms:

(1.4a - 0.9a) + (-1.2b + 1.2b)

= 0.5a + 0b

= 0.5a

Therefore, the simplified expression is 0.5a.
