So first of all write down 82 / 12 and do the problem.Divide 82 / 12.
Next you get the answer which is,based on a calculator,which is <span>6.83333333333.
But because it's money well I'm guessing it could be 6.83 or 6.833 or the real answer.
The question is confusing but I hope I could help :D</span>
        
             
        
        
        
Answer:
a) one solution
b) no solution
Step-by-step explanation:
Systems of equations can be described as having one solution, no solution or infinite solutions: 
One solution:  'x' and 'y' are equal to only one value
No solution:  'x' and 'y' can not be solved with the given equations 
Infinite solutions:  values for 'x' and 'y' include all real numbers 
In order to evaluate the systems, putting them in the same format is your first step: 
a) - y  = -5x - 6 or y - 5x = 6
    y - 5x = -6 
Since both equations have the same expression 'y - 5x', but there are equal to opposite values, this system would have no solution, as this would not be possible to calculate. 
b) y + 3x = -1 
   y = 3x -1 or y - 3x = -1
Solving for 'y' by adding the equations and eliminating 'x', gives us:
2y = -2 or y = -1 
Using y = -1 to plug back into an equation and solve for 'x':  -1 + 3x = -1 or x = 0.  Since 'x' and 'y' can be solved for a value, the system has just one solution. 
 
        
             
        
        
        
Answer:
Option D
Step-by-step explanation:
Formula for the surface area of rectangular prism = 2(lb + bh + hl)
Here, l = Length of the prism
b = Width  
h = Height
If l = 25 cm, b = 12 cm and h = 20 cm
Surface area of the rectangular prism = 2(25×12 + 12×20 + 20×25) cm²
Therefore, Option D will be the correct option.
 
        
             
        
        
        

Now, multiply both sides by 6 and you get.....
 df+10=6g
now, subtract 10 on both sides and you get.....
df=6g-10
now divide both sides by d to get f by itself and you get........
