Answer: 8
Step-by-step explanation:
Given
Lian has  and she has twice as many dimes as nickels
 and she has twice as many dimes as nickels
Suppose she has  nickels
 nickels 
So, the number of dimes is 
Nickel is equivalent to 5 cents and dime is equivalent to 10 cent

Therefore she has 8 dimes with her.
 
        
             
        
        
        
Solution:
As given Square L M NO is dilated by  a scale factor of two about the center of the square to create square L'M'N'O'.
Original line of Dilation = Along P Q
New Dilated line = P'Q'
As scale factor > 1
1. Image Size > Pre image size
2. The two images will be similar.
3. Length of Dilated Line P' Q' = 2 × Length of PQ
As you can see from the diagram drawn below, Dilated line P'Q'  will contain the point P and Q.
All four points P,Q,Q',P' are collinear , lie in the same line.
Option (2) dilated line P'Q' will contain the points P and Q is true.
 
        
                    
             
        
        
        
Answer:
Let's use the slope-intercept form of the equation of a line describe the slope and the y-intercept:
 y = mx + b where m=slope and b=y-intercept
 
 
        
                    
             
        
        
        
Answer:
19.26
Step-by-step explanation:
7% of 18 is 1.26
1.26+18=19.26
 
        
             
        
        
        
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
                but 2 is not a fraction
