(9b + 5) + (3b – 6)

12b-1

I hope this helps

to double check it I asked my math teacher if it was right

he said it is so there ya go.

i would pic false cause it goes down towards negative

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
