Answer:
25 = x
Step-by-step explanation:
If the angles are congruent, they are equal
5x+15 = 6x-10
Subtract 5x from each side
5x+15 -5x = 6x-5x-10
15 = x-10
Add 10 to each side
15+10 = x-10+10
25 = x
 
        
                    
             
        
        
        
522 divide 9= 58           58=1hour   58 x 4=232 add 232 to 522 =754
        
                    
             
        
        
        
a is the answer as the only change is the gradient being halved, 
b would be if it was -1/2 and c would be1/2 x+1/2
 
        
             
        
        
        
Answer:
7.5% error
Step-by-step explanation:
Percent Error = ( | measured - real | / real ) x 100%
|430 - 400| / 400 = |-30| / 400
( 30 / 400 ) x 100%
= 7.5%
