3.5x - 1 = -1/2(-7x + 2)
3.5x - 1 = 7/2x - 1 By virtue of the distributive property
7/2 = 3.5, so there is no solution. The statement is true for any value of x.
Essentially it boils down to -1 = -1, which is always true.
Answer:
50.82
Step-by-step explanation:
3x+2=x+2x+4
-2 -2
3x=x+2x+4-2
3x=3x+4-2
-3x -3x
x= 4-2
x=2
Answer:
1017.9 ft^3
Step-by-step explanation:
We know the inside dimension at floor level will be 18 feet across, so that may not be the answer that is being asked for. We also know it will be 12 ft high inside, so that may not be the answer, either. We're not quite sure what "how big" is supposed to mean.

Perhaps the question is trying to ask for the volume of the teepee. That will be given by the formula ...
V = (1/3)πr^2·h
V = (1/3)π(9 ft)^2·(12 ft) = 324π ft^3
V ≈ 1017.9 ft^3
The interior volume will be about 1017.9 cubic feet.
