Answer:
x = -36, y = 6, z = -6
Step-by-step explanation:
The requirement x/z = -z means x = -z².
The requirement x/y = z means x = yz.
These two requirements together mean yz = -z², or y = -z.
The requirements that z/2 and z/3 are integers mean that z is a multiple of 2·3 = 6. The smallest magnitude non-zero multiple is z=-6 (since we also require z < -z).
Using z=-6, we have x = -z² = -36; y = -(-6) = 6.
For some positive integer n, ...
... x = -36n², y = 6n, z = -6n.

Answer:
Second Man = (2 Hours * 1.3333 Hours) / (2 Hours - 1.3333 Hours)
Second Man = (2.6666666667 ) / (.666666667)
Second Man (when working alone) = 4 Hours
Step-by-step explanation:
<span>Ok, so we need to find the unit rate of 15 degrees in
2 hours.
this is a very simple question, it says here that in 2 hours, there are 15
degrees.
Thus we need to find the unit rate of
this given situation per hours.
=> hour many hours are there? The answer
is 2
so let us divide 2 by 15 to get the unit rate of the given situation
=> 15 degrees / 2 hours
=> 7.5 degrees / hours
Thus, the unit rate of 15 degrees per 2 hours is 7.5 degrees per hour.</span>
