Question

1.3b+7.8-3.2b Combine like terms pls

Answer 1

Answer:

−1.9b + 7.8

Step-by-step explanation:

This is the answer because:

1) Like terms are numbers or variables that are the same/ "alike"

2) 1.3b and -3.2b are like terms, so we have to combine them

3) 1.3b - 3.2b = 1.9b

4) Finally, 7.8 is the number that is left. This is not a like term in this expression because it does not have the same variable.

Therefore, the answer is  -1.9b + 7.8

Hope this helps!
