Answer:
72 lbs
Explanation:
Tail weight is TW.
Head weight is HW.
Body weight is BW
TW=9 lbs.
HW=TW+(BW/2)
BW=TW+HW
[tex]TW=9\\HW=TW+(BW/2)\\BW=TW+HW\\BW=HW+9[/tex]
Since HW=BW/2+9 inserting it in BW=HW+9
[tex]BW=9+(BW/2)+9\\BW=18+(BW/2)\\BW-BW/2=18\\\\BW/2=18\\BW=36\\Total weight=BW+HW+TW[/tex]
Inserting BW value in HW=9+BW/2
[tex]HW=9+(36/2)\\HW=27\\TW=9\\Total Weight=36+27+9\\Total Weight=72 lbs[/tex]
