He maybe accidently added both of thm .
But if we difference we get 7.
Because - and - =+
So
-11+4=7.
1.the flight from Baltimore to Miami is 2 hours and 35 minutes
2.the flight to Boston from Baltimore is the shortest.
Miami = 2hrs 35min
Boston = 1hr 15min
Atlanta = 1hr 55min
Indianapolis = 1hr 40min
The factors of 96 are 3,5,7
We want to solve 4|p-3| = |2p+8|
Ths equation is equvalent to 4 equatons.
Case 1.
4(p - 3) = 2p + 8
4p - 12 = 2p + 8
2p = 20
Answer: p = 10
Check the solution.
4|p-3| = 4*7 = 28
|2p+8| = 2*10+8 = 28
The solution is correct.
Case 2.
4(3 - p) = 2p + 8
12 - 4p = 2p + 8
4 = 6p
Answer: p = 2/3
Check the solution.
4|p-3| = 4*|(2/3-3)| = 28/3
|2p+8| = 28/3
The solution is correct.
Case 3.
4(p-3) = -2p - 8
4p - 12 = -2p - 8
6p = 4
Answer: p = 2/3
The solution is correct because it was checked in case 2.
Case 4.
4(3 - p) = -2p - 8
12 - 4p = -2p - 8
20 = 2p
Answer: p = 10
The answer s correct because t was checked in Case 1.
Answers:
p = 10 or p = 2/3.
Both answers check out to be correct.
