Answer:
B
Step-by-step explanation:
3% = 3/100 
So we can eliminate the first answer.
The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it. 
As a result, we eliminate the third answer and remain with one reasonable answer
 
        
             
        
        
        
Answer:
{3,-1}
Step-by-step explanation:
m^2 -2m -3=0
What 2 numbers multiply to -3 and add to negative 2
-3* 1 = -3
-3 +1 =-2
(m-3) (m+1) =0
Using the zero product property
m-3 = 0  m+1 =0
m=3        m=-1
{3,-1}
 
        
             
        
        
        
Answer: -8 is the answer.
Step-by-step explanation:
according to the question:
{{(8+4)*5}/(-10)}-2
= {[12*5}/(-10)]-2
= [60/(-10)]-2
= -6-2 = -8
 
        
                    
             
        
        
        
2(x - 5) = 110
2x - 10 = 110
Add 10 to both sides.
2x = 120
Divide by 2 on both sides.
x = 60
