Answer:
One Solution ; x=4.5
y=-1.5
Step-by-step explanation:
Line A: 2x+2y=8
÷<u>2</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
x+y=4
Line B: x+y=3 -----> y=x-3
x+(x-3)=4
2x-3=4
2x=7
x=4.5
y=-1.5
I think it is 18 Hope this helps. :)
Commercial passenger flights always list the time AT THE PLACE where
the event took place. The data you gave in your question means that the
flight departed ORD at 8:00 AM Central (Chicago) Time, and arrived LAX
at 12:00 PM Pacific (Los Angeles) time.
Since the trip spanned two time zones, it was actually in the air for 6 hours.
Average speed = (distance) / (time to cover the distance)
= (1,700 miles) / (6 hours) = (283 and 1/3) miles per hour.
====================================
But that wasn't what you had in mind, was it.
You meant that the flight took 4 hours.
In that case, the average speed was
(1,700 miles) / (4 hours) = 425 miles per hour.
This is a much more reasonable average speed for a long haul
passenger jet airliner.
Answer:
probably no one can
Step-by-step explanation:
You can't simplify this equation anymore because they have no like terms.
