Let's say the speed of the plane is "p", and the speed of the wind is "w".
when the plane goes with the wind, is not really going "p" mph fast, is really going "p + w" mph fast, because the wind is adding speed to it.
likewise when the plane is going against the wind, is also not going "p" fast is going "p - w" mph fast. Therefore,
5 + (-6) = -1
hope this helps!
Answer:
I got -437
Step-by-step explanation:
Lets break it down.
12x - 3y4x - z
If you substitute the numbers for its given variable, you should get
12(3) - 3(13)4(3) - 5
Now, just multiply and subtract to simplify.
36 - 468 - 5
<u>-437</u>
