9×2=18. add the tow zeros like this 9×2=18+00=1,800
The answer is B ! Hope this helps !
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.
If you subtract $43.78 by $27.86 you'd get $15.92 cents left. And if you take that and divide it with $3.98 cents you would get the answer choice C : 4 notebooks
The formula is X=8. hope it helps
