To answer the question presented above, the conversion factor for km to feet is 1 kilometers is equal to 3280.84 feet. From the given,
(12 km) x (3280.84 ft / 1 km) = 39370.08 feet
Thus, Joe traveled an approximate distance of 39370 feet.
It MUST be a right triangle for this formula to work, please comment if it is not a RIGHT triangle

a and b being the lengths of the legs of the triangle (the 2 sides that are not the hypotenuse) and c being the hypotenuse's length.
The best way to do this question is to use elimination. Elimination is a way to find out the POINT OF INTERSECTION between two lines. Let me show you how.
3y+4x=3
x+3y=-6
Elimination is a way to remove any same variable with the same coefficient. In this case, there is 3y in both equations. In this case, we subtract to eliminate.
3y-3y+4x-x=3+6 It's plus 6 because two negatives become positive.
3x=9 Divide both sides by 3
x=3
Now you can find y.
x+3y=-6
3+3y=-6
3y=-9
y=-3
Therefore, the POI is (3,-3). I hope you understand this. Make sure to mark as brainliest.
