I can immediately cross out D and C. I'm stuck between A and B, but i think it is A.
Ms. Sue forgot to grasp the concept of this being algebra not 1st grade math. I'll save you the time. It's 3.43.
Just curious, every math question on tests I've found on the internet because of another student asking, and they got an answer. This leads me to believe, litterally no one does there own work on connexus they just look it up, am I half right? 😂
