Answer:
The question is kinda funny. I think the graph isn't correct cos a and b coordinate ain't right
Firstly, you would subtract 7 from both sides, leaving you with 3m=21. You would then divide by three in order to be left with total value of m. 3m divided by 3 is m. 21 divided by 3 is 7. Therefore m=7 :)
77.27 ft rounded to the nearest tenth is 77.3 ft
It would be OD because it is going down by 8 each time and you can see that D goes down by 8 each time
