Answer:
9 hours
Step-by-step explanation:
We can use a ratio to solve
819 miles 567 miles
-------------- = --------------
13 hours x hours
Using cross products
819 x = 567*13
Divide each side by 819
819x/819 = 567*13/819
x =9
The answer should be 664 in squared
5x-8y=1...(1)
3x+6y=-21...(2)
(1)*3:
15x-24y=3...(3)
(2)*5:
15x+30y=-105...(2)
(3)-(2):
15x-24y-(15x+30y)=3-(-105)
15x-24y-15x-30y=108
-54y=108
y=-2
