Answer:
Step-by-step explanation:
- 162 total guests.
 - 3 servers
 
Let the number of guests the second server helped be x.
then the first server helped 3x
then the third server helped [(3x)*2] = 6x
Equation in total:
                                6x + 3x + x = 162
                                 10x = 162
                                    x = 16.2
- First server helped: 3 * 16.2 = 49 guests
 
- Second server helped: 16 guests
 
- Third server helped: 6x = 6(16.2) = 97 guests
 
 
        
             
        
        
        
Answer:
2 solutions
Step-by-step explanation:
Set up a system of equations. The absolute value produces two equations because one answer will be negative and the other positive.
d + 4 = -9
d + 4 = 9
So...
d = -13
d = 5
