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.

Step-by-step explanation:
After 2 hours time , both Abe and Gabe to cost the same amount .
<u>Step-by-step explanation:</u>
Here we have , a car needs fixing and Abe can fix it for $70 per hour with a $60 part, but Gabe can fix it for $80 an hour with a $40 part. We need to find How long will it take for both Abe and Gabe to cost the same amount .Let's find out:
Let the time for which both Abe and Gabe to cost the same amount be x hours, so according to question scenario we will have equation as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , After 2 hours time , both Abe and Gabe to cost the same amount .
