Answer:
<h2>The speed of the airplane is 475 miles/hour and the wind is 25 miles/hour.</h2>
Step-by-step explanation:
Let, the speed of the airplane is x miles/hour and the wind is w miles/hour.
With the wind, the speed will be (x + w) miles/hour and against the wind, the speed will be (x - w) miles/hour.
As per the given question, or, w = x - 450.
Now, .
Thus, w = 475 - 450 = 25.

Answer:
-2
Step-by-step explanation:
Let Oliver's number be x.
He multiplies it by 5:
x * 5 = 5x
He then subtracts 26:
5x - 26
Then, he divides by 6:
He then multiplies his original number by 3, and gets the same answer.
This implies that:
Let us simplify this:
Collecting like terms:
Oliver's number is -2.
