The area of the sector is given by the equation,
                           A = πr²(x / 360°)
where x is the number of degrees in the figure. 
                           25π ft² = (πr²)(60/360)
The value of  r is 12.25 ft. Then, we use this value to calculate for the circumference of the sector. 
                           C = 2πr(x/360)
Substituting,
                              C = 2π(12.45)(60/360)
                                   C = 12.83 ft³
        
             
        
        
        
Step-by-step explanation:
-2x+3=x+12
combin like terms
-2x-x=12-3
-3x=9 
x=9/-3
x=-3
 
        
                    
             
        
        
        
Answer:
3
Step-by-step explanation:
The goal is to get the x to be on one side of the equation on its own. 
-6x = -18
To get rid of the -6, we would have to do the opposite of what it's doing in the equation - in this case, we would divide, as it's the opposite of multiplying.
What we do to one side of the equation, we have to do to the other. 
-6x/-6 = x
-18/-6 = 3
x = 3
Hope that makes sense!
