Answer:
 x = 2
Step-by-step explanation:
2(2x+1-x)=6
2(x+1)=6               add common factors
2x+2=6                distribute the 2
2x=4                     subrtract 2 on both sides
x=2                        divide 2 on both sides
 
        
             
        
        
        
Sarah will need 1/4 cup of blueberries to make a cup of jam.
        
                    
             
        
        
        
5u - (-20u) - u - 18u + (-11u) = 10
5u + 20u - u - 18u - 11u = 10
-5u = 10
-5(-2) = 10
So, in conclusion, X, is equal to -2.
        
             
        
        
        
Answer:
C. 2448π units³
Step-by-step explanation:
V = π·r²·h
= π·12²×17
= 144×17·π
= 2448π units³
 
        
             
        
        
        
The answer is C 
1/2(5x + 12) 
because the perimeter is equal 20x + 6
