Answer:
each person owe $10.26
Step-by-step explanation:
Six friends go out to lunch and decide to split the bill evenly. The bill comes to $61.56.
Total bill for 6 friends = $61.56
To find bill cost for 1 person we divide the total cost by 6
Bill for each person = 
So each person owe $10.26
You would have to find the unit rate which is 26 feet per 1 minute (52/2) Otherwise you are correct
Anwser: (-1,-5)
Why:
All you have to do is plug in the coordinates into the equation...
(5,10):
10+5=2(5+1)
15=10+2
15=12
This is false so this ordered pair isn’t a solution
(-1,-5):
-5+5=2(-1+1)
0=-2+2
0=0
This statement is true therefore this ordered pair is a solution and is the only solution.
18.5 would be the answer and here’s my work
