You can put this solution on YOUR website! The correct answer is D. You can tell this by using the question. First, the fact that Antonio rides his bike 7.3 miles to school. Second, he wants to change it so the he rides 4 MILES LESS THAN TWICE THE DISTANCE he is riding. This is key. Let's take it apart: twice the distance would be 2 times the distance (7.3). 4 miles less would be -4. So the number of miles (m) would be 2(7.3)-4=m.
