Answer: Santa's speed in still air is 6 miles per minute
Speed of the wind is 1 mile per minute
Step-by-step explanation:
Let x represent the speed of Santa in still air. It is assumed that in still air. She is flying with the wind. If the speed of the wind is y, then him total speed is x + y
It takes Santa 5 minutes to fly 35 miles with the wind.
Speed = distance / time
It means that
x + y = 35/5 = 7
It takes him 7 minutes to fly 35 miles against the wind. This means that his total speed will be x - y
Speed = distance/time. Therefore,
x - y = 35 /5 = 5 - - - - - - 1
Substituting x = 7 - y into equation 1, it becomes
7 - y - y = 5
-2y = 5 - 7 = -2
y = -2/-2 = 1
x = 7 - y = 7 - 1
x = 6
Answer: I think it is the reflexive property
Step-by-step explanation:

Answer:
<em>3p + 89 < 765</em>
<em>Correct answer: D.</em>
Step-by-step explanation:
Austin, his dad, and brother make a group of three people of varying weights. Assume their average weight is p and their total weight 3p.
The cooler and other supplies weigh 89 pounds in total.
The weight of the supplies and the three people in the canoe should not be equal or exceed the maximum allowable weight of the canoe of 765 pounds.
This leads to inequality:
3p + 89 < 765
Correct answer: D.
