Several cross country runners were running one morning. Carlos had a 20 meter head start, Angela had a 30 meter head start, and Juan had a 35 meter head start. Susan had no head start. The tables below show each person’s distance at a specific time in the race. Which table shows a proportional relationship?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
