Answer:
B
Step-by-step explanation:
When you are solving these kinds of problems, it's always best to start with getting rid of the decimal/fraction.

We can actually solve for a.
2/3*3=6/3=2
(15+2a=-5)
a=-10
(15+(-20)=-5)
TRUE
a=10 (I think)
Volume of the pyramid = 40 cubic units
Solution:
Let us find the volume of the pyramid.
Area of the base = 

= 10 square units
Area of the base (B) = 20 square units
Height of the pyramid = 12
Volume of the pyramid = 

cubic units
Volume of the pyramid = 40 cubic units
Answer: $32.22
Step-by-step explanation:
Answer:
- x = 37
- DG = 22
- AG = 44
- AD = 66
Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Of course, AD = AG +GD = 44 +22 = 66
