Answer 2

Let's simplify the given expressions:

1. 0.24b + 9.76b - 16b

To simplify this expression, you can combine like terms by adding or subtracting the coefficients of 'b'.

0.24b + 9.76b - 16b = (0.24 + 9.76 - 16)b

Now, perform the arithmetic inside the parentheses:

0.24 + 9.76 - 16 = -5

So, the simplified expression is:

-5b

2. -3.9c - 4.2c + 1.5c

Similarly, let's combine like terms by adding or subtracting the coefficients of 'c'.

-3.9c - 4.2c + 1.5c = (-3.9 - 4.2 + 1.5)c

Now, perform the arithmetic inside the parentheses:

-3.9 - 4.2 + 1.5 = -6.6

So, the simplified expression is:

-6.6c
