The absolute value measures the distance a number is away from the origin (zero) on the number line. A number can be to the left or right of zero on the number line, but the distance away from zero is always positive. Graphically:
In other words:
• If d is positive and

• If d is negative and

Therefore, the equation that has no solutions is:
 
 
        
             
        
        
        
It has 4 equal sides, but it can be "squished" so all 4 angles are not equal
        
                    
             
        
        
        
Answer:
100 girls
Step-by-step explanation:
The ratio of boys : girls is 2 : 5.
In other words, boys are 2 parts of the school while girls are 5 parts of the school.
Since there are 40 boys, 2 parts of the school is 40. Thus:

1 part is 20.
Since there are 5 parts girls, there are

100 girls.
