Answer 1

Answer:

$2.4b+4c$

Step-by-step explanation:

Simplify:

$-0.8b+4.1c-(-3.2b)-0.1c$

then;

$-0.8b+4.1c+3.2b-0.1c$

Like terms are those which have same variable to the same power.

Combine like terms;

$2.4b+4c$

Therefore, the simplified form of the given expression is, $2.4b+4c$

Answer 2

-0.8b+4.1c-(-3.2b)-0.1c
-(-3.2b)= 3.2b
4.1c-0.1c=4c
-0.8b+4c+3.2b
-0.8b+3.2b=2.4b

4c+2.4b
