Hello!
To find this ordered pair, we solve for x and y and put them together in an ordered pair.
-4+y=8
x-5y=17
Let's solve the first equation for y.
y= 12
Now, let's plug 12 into the second equation for y.
x-5(12)=17
x-60=17
x=77
Therefore, our ordered pair is (77,12)
I hope this helps!
 
        
                    
             
        
        
        
Answer:
B : 0.7
Step-by-step explanation:
Given:
Doug lives 7. Block away from his school.
Each block is about 265 feet long.
Question asked:
What is total round-trip distance,in miles that Doug walks to and from school each day ?
Solution:
Each block is about = 265 feet
7 Block = 
As he lives 7 block away from his school that means his round trip distance is,
7 block ( travel during going to school ) + 7 block ( when return from school )
<em>Therefore, his total round trip is 14 block, means 1855 feet + 1855 feet = 3710 feet.</em>
Now, we have to convert it into miles as here asked: (unitary method)
5280 feet = 1 mile
1 feet = 
3710 feet = 
                = 
Thus, total round-trip distance,in miles that Doug walks to and from school each day is 0.7 miles.
 
        
             
        
        
        
Let Kamil get x. Therefore Sean would get (x + 56).
Kamil and Sean are in the ratio:        3:5
That means:    x : (x + 56) = 3 : 5
x / (x + 56) = 3/5
5*x = 3*(x + 56)
5x = 3*x + 3*56
5x = 3x + 168
5x - 3x = 168
2x = 168
x = 168 / 2
x = 84
Therefore Kamil had, x = 84,  and Sean had (x + 56) = 84 + 56 =  140
Kamil had $84 and Sean had $140
