Students are planning a 3 day hiking trip in the Everglades. The hike covers a distance of 18.5 kilometers. The students hike .28 of the total distance the first day. If they split the remaining distance equally between the second and third days, how far will they hike on day 3?

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.
