Given parameters; 
   Let us solve this problem step by step;
Let us represent Simon's money by S
Kande's money by K 
- Simon has more money than Kande
                S > K 
-   if Simon gave Kande K20, they would have the same amount;
  if Simon gives $20, his money will be  S - 20 lesser;
       When Kande receives $20, his money will increase to K + 20 
                      S - 20  = K + 20   ------ (i)
- While if Kande gave Simon $22, Simon would then have twice as much as Kande; 
           if Kande gave Simon $22, his money will be K - 22
     Simon's money, S + 22; 
                   S + 22  = 2(K - 22)    ------ (ii)
Now we have set up two equations, let us solve; 
           S - 20  = K + 20  ---- i 
          S + 22  = 2(K - 22)  ;       S + 22  = 2K - 44  ---- ii
So,      S - 20  = K + 20 
           S + 22  = 2K - 44 
subtract both equations; 
                -20 - 22  = (k -2k)  + 64
                    -42  = -k + 64 
                        k  = 106
Using equation i, let us find S;
             S - 20 = K + 20
              S - 20  = 106 + 20 
               S = 106 + 20 + 20  = 146
Therefore, Kande has $106 and Simon has $146
 
        
             
        
        
        
5.5 ( 8 - x ) + 44 = 104 - 3.5 ( 3x + 24 )
Distribute 5.5 through the parenthesis.
44 - 5.5x + 44 = 104 - 10.5x - 84
Add the numbers.
88 - 5.5x = 20 - 10.5x
Move variable to the left side and change its sign.
88 - 5.5x + 10.5x = 20
-5.5x + 10.5x = 20 -88
Collect like terms.
5x = 20 - 88
Calculate the sum or difference. 
5x = - 68
Divide both sides by 5.
x = - 68 / 5
        
             
        
        
        
To find the average add all the numbers together then divide by how many numbers there are. 
75+80+97+92=344 divided by 4 = 86
So her average right now is 86. 
She’d have to make 96 to get an average of 88.
75+80+97+92+96=440 divided by 5=88
The answer is 96
        
             
        
        
        
Answer:
56.6 °
Step-by-step explanation:
For a RIGHT triangle    cos (x ) = adjacent leg / hypotenuse 
                                       cos (x) = 4.4 / 8 
                                             arc  cos (4.4/8) = 56.63 °  = ~ 56.6°
