Answer:
139
Step-by-step explanation:
57+67+45=169÷3=139
Use similar volume to calculate
which is the (ratio of edges)^3 = (ration of volume)
so just put the numbers in, let the volume of smaller pyramid be y.
(3/4)^3 = y/320
27/64 = y/320
y=135in3
2x + y - (x + y) = 3z - 6z
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------
<span>(-3z, 9z) </span>
----------------------------------
<span>(x,y,z) = (-3z, 9z, z)
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>
