Question

Two groups of campers, Group A and Group B, hiked two different routes from their campsite to a waterfall. Group A hiked through Vista Point to reach the waterfall. Group B hiked directly to the waterfall. The figure shows the distances they hiked.



Which simplified expression can be used to find the difference in the number of miles hiked by the two groups?

2x - 1

2x + 1

2x + 3

2x + 7

Answer 1

HELP PLZ!!!

Answer 2

Total distance for group A would be (x-1) + (2x+5) or 3x + 4. Total distance for group B would just be x + 3. All you need is the difference between these two, so that would be 2x + 1, so it was B...
