Answer:
Infinite solutions
Step-by-step explanation:
2x + y = 3
6x = 9 - 3y
2x + y = 3
6x + 3y = 9
3(2x + y = 3)
3(2x) + 3(y) = 3(3)
6x + 3y = 9
Answer:
none of them are correct
Step-by-step explanation:
The speed of the plane will be 200 knots.
You do 800/4 because you are trying to find the speed of the airplane.
If you take the speed of the plane and divide the distance by the speed and then followed by the 5 and 4, you will get 800/200/4/5
800/200
=400
400/4
=100
100/5
=20
The speed of the wind is 20 knots.
Answer:
54mph
Step-by-step explanation:
To find the speed in "miles per hour" or miles/hour, divide the number of miles by number of hours.
1080 miles/20 hours
= 54miles/hour
His speed is 54 miles per hour.
