Answer:
Expression Chang:
N+6 
If N = 60
Then 60+6=66
Chang is 66 inches 
Step-by-step explanation:
 
        
             
        
        
        
5x[$25.85-($25.85 x 0.10) ] + (5 x 2.50)=$128.83 compared to[ 5 x 27.36( $27.36 x 0.15)]+ 10.00= 126.28 is the least amount. 
answer is ------> $126.28
 
        
             
        
        
        
We can see that 
both lines intersects at origin
so, the solution is x=0 and y=0
now, we will check each options
option-A:


now, we can set them equal 
and then we can solve for x



now, we can find y 


so, solution is x=0 and y=0
so, this correct...........Answer
 
        
             
        
        
        
Answer:
The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"
Step-by-step explanation:
Given values:

After solve equation (a) we get

After solve equation (b) we get

put the value of x in to equation (x)


The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29
