Answer:
y=2x-1
Step-by-step explanation:
Answer:
B. 54
Explanation:
Take 72 from 180.
180 - 72 = 108.
Since there are two y's AND they're congruent, divide 108 by two and get 54.
The speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.
<h3>Relative Speed Concept;</h3>
When the plane flies against the wind;
- Relative Speed = 120 = x -y
When the plane flies with the wind;
- Relative Speed = 240 = x +y
Where in;
- The speed of the air plane = x
- The speed of the wind = y
By solving the equations simultaneously; we have;
- x = 180 miles in 2 hours and y = 60 in 2 hours.
Ultimately, the speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.

Answer:
See the attached file
Step-by-step explanation:
Given data
Say numbers of printer made per hour = 5 printers
Hence in 1 hour, they will make 5 printers
in 4 hours they will make
=4*5
=20 printers
The graph of this situation when plotted will give a straight line graph
