Answer:
0.6
Step-by-step explanation:
The x increases by 5, while y increases by 3
Lets use the method, which is 
.
Keep in mind that x goes horizontally along the axis, while y goes vertically on the axis.
So plug the numbers in.
 0.6
Hence, the constant proportionality is 0.6.
 
        
                    
             
        
        
        
Answer:
c would be the right and its the best answer
 
        
             
        
        
        
∠ABC is 180°. ∠ABC-∠ABD=68°. Since line BE ∠DBC, 68 divide by 2 is 34°. So ∠EBC is <span>34°.</span>
        
             
        
        
        
Sum means addition 
negative 18 means -18
a number can be x
Sum of negative 18 and x should be 11
thus the equation is
