Question

−1.5(4−n)+2.8 simplified is

Answer 1

Answer: 8.8 + 1.5n

Work:
The first thing you need to do is distribute the -1.5 to the terms within the parentheses. Doing so simplifies the expression to 6 + 1.5n +2.8. Then combine like terms, so the 6 and the 2.8, which simplifies the expression to 8.8 + 1.5n, which is the answer. 

Answer 2

Answer

1.5n-3.2

Explanation

First, we need to distribute -1.5. To do it we just multiply each term inside the parenthesis by -1.5:

$-1.5(4-n)+2.8$

$-1.5*4-1.5*-n+2.8$

$-6+1.5n+2.8$

Now we just need to combine like terms:

$1.5n+2.8-6$

$1.5n-3.2$
