-2/(a+b)
Explanation: you are dividing negative two by the sum of a and b so you would put a+b in parentheses as the denominator and then put -2 as the numerator
Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
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.
