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!
