<span>The best answer is: subtract 1, subtract 3x, then divide by 3.
Subtract 1 gives: 3x-4=6x
Subtract 3x gives: -4=3x
Divide by 3 gives: x=-4/3
None of the others work, because you either end up with the variable and the constant on the same side (can't isolate the variable!) or you end up with the wrong sign on the coefficient of the variable from what is stated (e.g., 2nd option).</span>
Answer:
the formula for the volume of a square pyramid is V=a^2*h/3
so if we just put in the data
12^2*10/3
144*10/3
480
so the answer is B
Hope This Helps!!!
Simplify the left side
4c+9=37
Move all terms NOT containing C to the right side of the equation
4c=28
Divide each term by 4 and simplify
28 divided by 4
Answer
C=7
