Answer:
 In the last task, the result is 17+3x/6
Step-by-step explanation:
X+5/3 - 2x-7/6 + x/2
2(x+5)-(2x-7)+3x <em>/</em><em>6</em>
2x+10-2x+7+3x <em>/</em><em>6</em>
17+3x/6
I dunno this task above, I hope this one is correct :))
 
        
             
        
        
        
Answer:
 The system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234 
Step-by-step explanation:
Let us assume that the number of small dogs groomed be x.
Let us assume that the number of lagre dogs groomed be y.
As given
Paws at play made a total of $1,234 grooming 22 dogs.
Than the equation becomes
x + y = 22
 Paws at play charges $43 to groom each small dog and $75 for each large dog. 
Than the equation becomes
43x + 75y = 1234
Therefore the system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234
