Answer:
x = y/5 + 6/5
Step-by-step explanation:
Solve for x:
5 x - y = 6
Add y to both sides:
5 x = y + 6
Divide both sides by 5:
Answer:  x = y/5 + 6/5
 
        
             
        
        
        
Step-by-step explanation:
TanA = SinA/CosA
                                  tanA = 2xy / (x² + y²),
                                  Sin A = CosA * 2xy / (x² + y²)
 
        
             
        
        
        
Answer:
x=2
Step-by-step explanation:

Add 14 to both sides

Square root it
x=2
 
        
             
        
        
        
7 times of 1/2 cup  = 7 x 1/2 
7 times of 1/2 cup  = 7/2
7 times of 1/2 cup  = 3 1/2 cups.
