Answer:
The equation shows the commutative property of addition is 4 +3 = 3 + 4 .
Option (A) is correct.
Step-by-step explanation:
Commutative property of addition
The commutative property for addition states that
a + b = b + a .
Where a, b are any number.
thus
this above condition is satisfied by equation
4 + 3 = 3 + 4
7 = 7
Therefore Option (A) is correct.
Given:
A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.
Pilot's speed in still air is 315 miles per hour.
To find:
The speed of the wind.
Solution:
Let the speed of wind be x miles per hour.
Speed with wind = 315+x miles per hour
Speed against wind = 315-x miles per hour
We know that,

According to the question,

Divide both sides by 90.

By cross multiplication, we get




Divide both sides by 9.


Therefore, the speed of wind is 35 miles per hour.

Answer:
4750
Step-by-step explanation:
475000/100 = 4750
4750 * 6 = 28500
4750 * 5 = 23750
28500 - 23750 = 4750
