For x = -3, <span>(-0.7x) equals (-0.7[-3]), or 2.1.
 
                                8                   8                       8
Then f(-3) =  ------------------- = ---------------- = ------------ = 0.31 (approx)
                        1 + 3*e^2.1      1 + 24.499        25.5</span>
        
             
        
        
        
Angle B equals angle D 
angle A equals angle C
so △ABE =△CDE
i think thats the answer
        
                    
             
        
        
        
Well if the ratio is 5:1 that's 5 pancakes:1 flour so it would be 14 flour needed
        
             
        
        
        
<span>Simplifying
2x + -3 = -1x + 3
 Reorder the terms:
-3 + 2x = -1x + 3
 Reorder the terms:
-3 + 2x = 3 + -1x
Solving
-3 + 2x = 3 + -1x
 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side  of the equation.
-3 + 2x + x = 3 + -1x + x
 Combine like terms: 2x + x = 3x
-3 + 3x = 3 + -1x + x
 Combine like terms: -1x + x = 0
-3 + 3x = 3 + 0
-3 + 3x = 3
 Add '3' to each side of the equation.
-3 + 3 + 3x = 3 + 3
 Combine like terms: -3 + 3 = 0
0 + 3x = 3 + 3
3x = 3 + 3
 Combine like terms: 3 + 3 = 6
3x = 6
 Divide each side by '3'.
x = 2
 Simplifying
x = 2
answer x=2
