Answer:
n ≥ -3
Step-by-step explanation:
So, divide -27 by 9n and the answer to that is -3, because when you're dividing a negative number and a positive, the answer would always be negative.
This sign : ≥ means greater than or equal to, and because we are solving for n, -3 is equal to n.
9,000 * 3% = 270
So it would be $270 in sales tax
Answer:
10.
Step-by-step explanation:
I am assuming that z is a whole number.
160z = x^2
z = x^2/ 160.
160 = 2*2*2*2*2*5
To make this a perfect square we multiply by 2 * 5
- this gives us 1600.
z = 1600/160 = 10.
