Answer 2

a) 9b - 5b + 3b + b

To solve this expression, we need to combine like terms. Like terms are terms that have the same variable and exponent.

In this case, we have terms with the variable "b". Let's combine them:

9b - 5b + 3b + b = (9 - 5 + 3 + 1)b

Now, we can simplify the expression:

(9 - 5 + 3 + 1)b = 8b

So the simplified expression is 8b.

b) 3m * 8a + c

To simplify this expression, we can multiply the coefficients and combine the variables:

3m * 8a + c = 24ma + c

So the simplified expression is 24ma + c.

c) 3(1.5x - 7) + 5x

To simplify this expression, we need to distribute the 3 to both terms inside the parentheses:

3(1.5x - 7) + 5x = 4.5x - 21 + 5x

Now, we can combine the like terms:

4.5x - 21 + 5x = (4.5x + 5x) - 21

Combining the x terms:

(4.5x + 5x) - 21 = 9.5x - 21

So the simplified expression is 9.5x - 21.

I hope this helps! Let me know if you have any further questions.
