base=3.3=cm
Step-by-step explanation:
9.1 cm
 
        
             
        
        
        
Ballance method is just a fance method of helping you remember to DO THE SAME THING TO BOTH SIDES OF AN EQUATION to keep it ballanced
-10=2(-3x+1)
divide BOTH SIDES by 2 to get rid of that 2 in front
-5=-3x+1
minus BOTH SIDES 1
-6=-3x
divide BOTH SIDES by -3
2=x
-x-7=-12
add7 BOTH SIDES
-x+7-7=-12+7
-x+0=-5
-x=-5
multiplY BOTH SIDES -1
x=5
        
             
        
        
        
The first thing we must do is define a variable.
 We have then:
 x: Linda's speed.
 Then, by definition, the time traveled is equal to the distance between the velocity.
 We have then:
 For Linda:
  
 For Miguel:
  
 Then, since time is the same, then:
  
 Clearing Linda's speed we have:
  
  
  
  
  
  
 Then, Miguel's speed is:
  
 Answer:
 Linda's speed is 10 Km/h
 Miguel's speed is 14 Km/h
 
        
             
        
        
        
The answer is C because it is telling you to subtract 180 degrees from 54 degrees to get the final answer which is 126 I got that because 54 is that angle and it is asking for the whole amount so it would be C
