Answer 2

To simplify the given expressions, let's start with each one:

A) $5(3a + b) - 15a$

To simplify this expression, you need to distribute the 5 into the parentheses and then combine like terms:

$5(3a + b) - 15a = 15a + 5b - 15a$

The $15a$ and $-15a$ terms cancel out because they are additive inverses, leaving you with:

$15a + 5b - 15a = 5b$

So, the simplified form of expression A is $5b$.

B) $2(a + 5b) + 6(0.5a - b)$

Let's simplify this expression step by step. First, distribute 2 and 6 into their respective parentheses:

$2(a + 5b) + 6(0.5a - b) = 2a + 10b + 3a - 6b$

Now, combine like terms:

$2a + 3a = 5a$

$10b - 6b = 4b$

So, the simplified form of expression B is $5a + 4b$.
