Answer:
72
Step-by-step explanation:
3(20+4)=a0
60+12=a0
72=a0
im not quite sure what you want. I solved for a0. Plz tell me if this is correct. If its not, tell me what u need, then I will solve it for you. 
 
        
                    
             
        
        
        
Answer:
13) 7 + x/2 = 10
14)  2x - 5 = 7
15) 4x - 1 = 11
16) 6x - 6 = 12
17) x/3 + 10 = 12
18) 2x + 7 = 1
19) 9 + x/7 = 11
20) 8(n - 3)
Step-by-step explanation:
The quotient of x and 2 = x ÷ 2 = x/2
The product is the result of multiplying two or more other numbers 
The sum is the result of adding two or more numbers 
The difference is the result of subtracting one number from another
13) 7 + x/2 = 10
14)  2x - 5 = 7
15) 4x - 1 = 11
16) 6x - 6 = 12
17) x/3 + 10 = 12
18) 2x + 7 = 1
19) 9 + x/7 = 11
20) 8(n - 3)
 
        
             
        
        
        
Step-by-step explanation:
sinx = a/b
tanx= a/c
cosx= c/b
 
        
             
        
        
        
Answer:
6/11, 15/21, 9, 27/37, 31/54
Step-by-step explanation:
Absolute value is when you determine the distance between a value and zero . Since you will always have a positive distance, your absolute values are positive as well.
 
        
             
        
        
        
We can take prime numbers so they don't have a common factor other than 1.
3, and 5.
So we have to list the multiples to find the LCM
3: 3, 6, 9, 12, 
15, 18
5: 5, 10, 
15, 20, 25
15 is the LCM of 3 and 5
So, you can notice that if two numbers, lets call them a and b, have no common factor, then 

 is the LCM.
Hope that helped :)
