I think it's 36. Because 7x3=21 and 12x3=36
        
             
        
        
        
In a parallelogram, if two opposites are congruent, then the two opposites are equal. We apply this description to solve the problem.
∠O = ∠M since they are opposite
2x = 3x - 55
55 = 3x - 2x
55 = x
Total of all angles in the parallelogram is 360°
∠L + ∠N +∠O +∠M=360°
360° - ∠O -∠M = ∠L + ∠N note that ∠L =∠N
360° -110° -110° = 2∠N
70° = ∠N
Solving for Y,
∠N = 5Y = 70°
Y=70/5
Y=14
Therefore, the value of "x" is 55 and the value of "y" is 14. The answer is the letter "C".
        
                    
             
        
        
        
Answer:
The naswer to your question is: letter c)70
Step-by-step explanation:
Data
2 skeins of yarn cost $7
8 skeins of yarn cost $28
total = 20 skeins
cost = ?
Equation = she need s to buy 2 skeins of 8 a 2 skeins of 2
                   
    cost = 2 x $28 + 2 X $7
   cost = 56 + 14
   cost = $70
 
        
             
        
        
        
The answer to this problem is 
all real numbers except for 4. When looking at this function, one can see that most numbers are possible. But, the only number that won't be possible is four. That's because the fraction 

 will always equal something greater than or less than zero. Since it's never going to equal zero, and since there is already a 4, that means that the range of this function is 
all real numbers except for 4.
