To find the number of miles driven on one gallon, divide 420 by 20. that would be 21. multiply 21 by 65 to find the number of miles you can drive with 65 gallons.

Answer:</h2>
s = 18°
<h2>
Step-by-step explanation:</h2>
The figure has been re-labelled to show additional information and description and has been attached to this response.
As shown in the figure, line AB is a straight line.
The angles on the straight line are <em>6s + 2</em> and <em>4s - 2</em>
<em></em>
Since the sum of angles on a straight line is 180°, it therefore implies that;
<em>6s + 2</em> + <em>4s - 2 = 180°</em>
<em></em>
<em>Solve for s by collecting like terms and simplifying</em>
6s + 4s + 2 - 2 = 180
6s + 4s = 180
10s = 180
s = 18°
Therefore, the value of s is 18°
