Question

-2/5(15а+1/2в)+ 1/5в-4а

Answer 1

= -6a-1/5b+1/5b-4a= -10a

Answer 2

Let's simplify the given expression step by step:

-2/5(15a + 1/2v) + 1/5v - 4a

First, let's distribute the -2/5:

= -6a - 1/5v + 2/5a

Next, let's combine like terms:

= -4 2/5a - 1/5v

Finally, let's simplify the mixed number:

= -4.4a - 0.2v

Therefore, the simplified form of the expression is -4.4a - 0.2v.
