Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.

3. To get his blender he has to mow the lawn 3 times.
Ezpeezee:
Since we know the two angle measures equals 145...
(4x+5)+(6x-10)=145
Combine like terms and you get...
10x-5=145
Solve for x...
Add 5 on both sides and you get 150. Then divide by 10 and you get 15.
However, we arent finished yet... We still need to find XMN. The equation for m<XMN= 6x-10. PLUG 15 IN FOR X...
90-10
and that simplifies to 80 degrees.
Any questions?
