Width of the envelope = 5.6
<u>Step-by-step explanation:</u>
Let the width of the rectangle be x
Then the length of the rectangle will be 
Also the length of the plastic band to cover the front and back of the envolpe = 
To cover one side th band required is
=>
=>
=>
=>
=>39.4
We know that the perimeter of the rectangle is
=> 2( L + B) = 
=> 2( 
) = 19.7
=> 2( 
=> 
=> 
=> 
Now length of the envelope =
=> 
=> 
=> 14

Step-by-step explanation:
1 - P winning - P losing = P drawing
1 - 0.3 - 0.55 = 0.15
4(y - 7) = 2y - 38
4y - 28 = 2y - 38
4y - 2y = -38 + 28
2y = -10
y = -5
