Answer:
5x + 6y = 32
5x - 6y = 8
eliminate the 6y, -6y
10x = 40
divide both sides by 10
x = 10
5(10) + 6y= 32
50 +6y = 32
6y = -18
y = -3
(10, -3)

Answer:
23,040 seconds.
Step-by-step explanation:
We have been given that a plane ride lasts 6.4 hours. We are asked to find the number of seconds, the plane ride lasted.
We know that 1 minute equals 60 seconds.
1 hour = 60 minutes = 60*60 (3600) seconds.
To find the number of seconds the plane ride lasted, we will multiply 6.4 by 3600.
Therefore, the plane ride lasted for 23,040 seconds.
I’m pretty sure that it would be x=0
