Answer:
Each friend will get 18 sea shells.
Step-by-step explanation:
Given:
Rudy has white sea shells = 10
Rudy has pink sea shells = 23
Rudy has brown sea shells = 21
Number of friends = 3
Rudy divides the sea shells into equally between three friends.
We need to find how many sea shells each friend can get.
Now first we find the total number sea shells.
Total number of sea shells = white sea shells + pink sea shells + brown sea shells = 10 + 23 + 21 = 54
Now to find number of sea shell each friend can get we will divide total number of sea shell with number of friends. 
number of sea shell each friend can get = 
Hence each friend will get 18 sea shells.
 
        
             
        
        
        
Answer:
   14 and 22
Step-by-step explanation:
If x is the first number, then 36-x is the second. We are told that ...
   2x -(36-x) = 6 . . . . twice the first less the second is 6
   3x = 42 . . . . . . . . . add 36
   x = 14
   (36 -x) = 22
The numbers are 14 and 22.
 
        
             
        
        
        
Answer:
4 1/12
Step-by-step explanation:
make all the denominators 12 so u can add them easier
2 1/12 + 2 4/12 + 3 2/12 = 7 7/12
nn subtract from the 11 2/3
11 8/12 - 7 7/12 = 4 1/12
 
        
             
        
        
        
Answer:
See below
Step-by-step explanation:
Expand L side to get 
4n -12   -2n  <  -10 + 2n     simplify L side
2n -12   <  -10 +2n      subtract 2n from both sides
<u>-12 < -10 </u>    <===== so the equation is true for ALL n 
(-∞  ,  + ∞ )
