Step-by-step explanation:
Andrew made a mistake at last step.
<u>It should be:</u>
- -11.8 + 9.8 = 9.8 - 11.8 = -2 but not -21.6
I assume you mean -5 and 3/4 instead of -53/4. In that case, it cannot be A, as -5.8 is less than -5.75 (AKA -5 3/4). It cannot be C or D either, though, as the number has to be less than -5.5, and -5.4 or -5.3 are both more than -5.5. Thus, by process of elimination, it has to be B, - 5.7. Hope I helped! Good luck in future!
