Let t, h, b represent the weighs of tail, head, and body, respectively.
t = 4 . . . . given
h = t + b/2 . . . . the head weighs as much as the tail and half the body
b/2 = h + t . . . . half the body weighs as much as the head and tail
_____
Substituting for b/2 in the second equation using the expression in the third equation, we have
... h = t + (h + t)
Subtracting h from both sides gives
... 0 = 2t . . . . . . in contradiction to the initial statement about tail weight.
Conclusion: there's no solution to the problem given here.
The answer is B. 8x+6. You multiple 3 and x+4 then combine like terms
The amount of balloons in the tent is 125.075 feet cube. From the given options, approximately, option D is correct
<u>Solution:</u>
Given, Rob is making a tent out of canvas in the shape of a square pyramid. Each side of the square base is 6 feet long, and the height is 6.3 feet.
Rob filled the tent with balloons,
We have to find which measurement BEST describes the amount of balloons in the tent?
As tent if filled with balloons the amount of balloons equals with volume of tent.
<em><u>Volume of tent is given as:</u></em>

where "a" is side length and "h" is height.

Hence, from the given options, approximately, option D is correct.
The answer is 0.5778 or 0.578 rounded
