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,
Answer: Equation
Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.

Answer:
X= 2
Step-by-step explanation:
Simplify.
5 + 3x + 4x = 19
Combine 3x + 4x = 7x
5 + 7x = 19
Solve.
5 + 7x = 19
Solving for variable 'x'.
Move all the terms containing x to the left, all other terms to the right.
Add '-5' to each side
5 + -5 + 7x = 19 + -5
Combine like terms: 5 + -5 = 0
0 + 7x = 19 + -5
7x = 19 + -5
Combine like terms: 19 + -5 = 14
7x = 14
Divide each side by '7'.
x = 2
Simplifying
x = 2
Hope this helps & good luck!
