Answer:
x=17, y=9. (17, 9).
Step-by-step explanation:
x+y=26
3x+8y=123
------------------
x=26-y
3(26-y)+8y=123
78-3y+8y=123
78+5y=123
5y=123-78
5y=45
y=45/5
y=9
x=26-9=17
 
        
             
        
        
        
Hello!
To find this you have to find what 55% of 20 is
You can do this by doing 20 * 0.55
0.55 is 55% as a decimal
This gives us the answer of 11
Hope this helps!
        
                    
             
        
        
        
Answer:
y=-3/4x-13/2
Step-by-step explanation:
This should be the answer, I am not 100% though
I did y-4=-3/4x(x+14)
 
        
                    
             
        
        
        
300miles/20sec=?miles/1min
900miles/60sec=?miles/1min
900miles/1min=?miles/min
?=900 miles
