Answer 3

It looks like you have an algebraic expression with terms involving the variable 'a'. To simplify this expression, you can combine like terms. In your expression:

2a - 0.7a - 1.9a

First, combine the 'a' terms:

(2a - 0.7a - 1.9a) = (2a - 0.7a - 1.9a) = (2a - 0.7a - 1.9a) = (2a - 0.7a - 1.9a)

Now, add the coefficients of the 'a' terms:

2a - 0.7a - 1.9a = (2 - 0.7 - 1.9)a

Now, simplify the coefficients:

2 - 0.7 - 1.9 = 0.4

So, the simplified expression is:

0.4a

The expression 2a - 0.7a - 1.9a simplifies to 0.4a.
