Answer:
 9in 
Step-by-step explanation:
54 = 1/2(12*x)
54 = 6*x
x = 9
Check
12 x 9 = 108
108/2 = 54

Answer: -2 73/100
Explanation: keep the -2 and just look at the .73. The .73 is in the hundredths place so you put it over 100.
        
                    
             
        
        
        
The first equation will go up by 2.5 and if it were changed to y=3X+2 it will go up by 8
        
                    
             
        
        
        
Answer:
The width of rectangle is 1 unit.
Step-by-step explanation:
Given:
The area of rectangle is 6 units and its width is 5 units less than the length.
So, to find the width of rectangle.
Let the length be  and the width be
 and the width be  .
.
Now, to find the width we put the formula of area of rectangle:
Area = length × width






<em>On solving equation we get:</em>

Therefore, we take the value x=6 as it is positive value:


So, the width of rectangle:
Width = 
           = 
           = 
Therefore, the width of rectangle is 1 unit.
