To construct a perpendicular bisector  you set the compass to a span which is greater than half the length of the given line.  Then setting the point at one end of the line construct an arc  passing through the line . Then repeat this process from the other side of the line keeping the compass at the same setting.
Now draw the perpendicular  bisector through the 2 intersections of the arcs. That's  it.

hope it help byeee
 
        
             
        
        
        
Simplify both sides of the equation 
-25(x-4)=-55(x-10)
(-25)(x) + (-25)(-4)=(-55)(x) + (-55) (-10) 
Distribute 
-25x+100=-55x+550
Add 55x  to both sides 
-25x+100+55x=-55x+550+55x
30x+100-100=550-100
subtract 100 from both sides 
30x+100-100=550-100
30x=450
divide both sides by 30 
30x/30=450/30
x= 15 
The value of x is 15 
I hope that's help you my friend ! 
 
        
                    
             
        
        
        
The answer is a=6, b=4, and 0=3 you can always try to find the answer in google though 
Hope that helped
