Convert 2.8 kilograms into 2800 grams.
Baby A weighs 2800 grams, baby B weighs 2950 grams -> The difference between the masses = 2950 - 2800 = 150 grams.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
A-5B = (2x+3) - 5(x²-5x+1)
   = (2x+3) + (-5x²+25x-5)
   = -5x² + 27x - 2
 
        
             
        
        
        
V = Volume of cylinder
B = area of base
h = height of cylinder
It turns out that
V = B*h
In a similar way to that of a cube
If we know that V = 84pi and h = 7, then we can plug those values into the formula above, and solve for B
V = B*h
84pi = B*7
84pi/7 = B*7/7 ... divide both sides by 7
12pi = B
B = 12pi
Therefore the base is 12pi square units
        
             
        
        
        
Identify and calculate formulas and examples...
Hope this helps ;)
 
        
        
        
Answer:
x = -4
Step-by-step explanation:
-5x-4x-2 = -8x+2 is the only one with a solution.
-5x-4x-2 = -8x+2
-x-2 = 2
-x = 4
x = -4
