I think it is 0.52
hop this helps XD
taking 2 to the other side ⇒
= 5 x 2
3x=10
taking 3 to the other side ⇒ x =
x = 3.34
So first you need to determine how much the minutes will cost him at most. Multiply 100(.20) and you will get 20. Add 20+45 which is 65. A reasonable range is $65.
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
