Answer:
m + n = 15
m - 3 = n
The numbers are 9 and 6
Step-by-step explanation:
From the question, 
The sum of two numbers is fifteen; the first number is m and the second number is n. To translate to a system of equations, we can write that 
m + n = 15 ..... (1)
Also, from the question, 
One number is three less than the other, 
Also, to translate to a system of equations, we can write that 
m - 3 = n ...... (2)
If desired, we can determine m and n
From equation (1) 
m + n = 15
Then, 
m = 15 - n ...... (3)
Put the value of m in equation (3) into equation (2)
m - 3 = n
Then 
15 - n - 3 = n
15 - 3 = n + n
12 = 2n 
n = 12/2
∴ n = 6
For m, put the value of n into equation 3
m = 15 - n
m = 15 - 6
m = 9
∴ m = 9 and n = 6
Hence, the numbers are 9 and 6
 
        
             
        
        
        
Answer:(3x-7) (3x-7) 
Step-by-step explanation:
9x2-42x+49
The two by the 9 is power of 2 so the small two above
 
        
             
        
        
        
Answer:
A. y = 1/2 x 
Step-by-step explanation:
A proportional relationship between two quantities is a collection of equivalent ratios, related to each other by a constant of proportionality. In other words, if each point on the line can be put as a fraction and reduced to the same fraction, the relationship is proportional. 
 
        
                    
             
        
        
        
So look at them
you have
'85 hundreths' and '75 hundreths'
85>75
therefor 0.85 is bigger
