The conclusion is that both gym charge the same, because the identity 75 = 75 means that the two equations are equivalent (the same).
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:
that will be b. :)
Step-by-step explanation:
Answer:
The angles measure 34 degrees and 146 degrees.
Step-by-step explanation:
The supplement measures x.
The angle measures x + 112.
The measures of supplementary angles have a sum of 180 deg.
x + 112 + x = 180
2x + 112 = 180
2x = 68
x = 34
x + 112 = 146
The angles measure 34 degrees and 146 degrees.
