Answer:
C
Step-by-step explanation:
You first distribute within the parentheses which is -(-z-2). This is going to make everything positive as everything in the parentheses is negative. You should get z+2. Next, you plug that back in. It should be-3z+z+2. You simplify to get -2z+2. Hope this helps!
 
        
                    
             
        
        
        
The simplest interpretation would go a little something like this:
We know that we want the total donation amount to be more than $7,900, so we can set up this inequality to begin with

Where 
D is the total donations raised (in dollars). How do we find D? Well, we just add up the total number of table reservations sold and the total number of single tickets sold. If we let 
r stand for the number of reservation tickets and 
s stand for the number of single tickets, then we have

So, the inequality representing this situation would be

And that would probably be fine for this problem.

Hello from MrBillDoesMath!
Answer:
I think your formula  (2y/x2) is equivalent to
(2*y)/(x^2)      where x^2 means x-squared.
If so, then
(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8
Thank you,
