Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.
4x^2 = 12x
4x^2 - 12x = 0
4x(x - 3) = 0
4x = 0
x = 0...not this one
x - 3 = 0
x = 3 <== ur number
2. 83 R 2
3. 82 R 1111 etc

The aircraft is 29238 ft from the ship
//
Note: this is based on my assumption that we are looking for the hypotenuse.
If we are looking for the adjacent side, then the answer would be 27475 ft.
