Homer the hungry hippo is munching on the lily pads in his pond. When he got to the pond, there ere 30 lily pads, but he is eating 5 lily pads an hour. Henrietta the hungrier hippo found a better pond with 38 lily pads! she east 7 lily pads every hour.
If homer and Henrietta start eating at the same time, when will their ponds have the same number of lily pads remaining.
After 4 hours they will have the same number of lly pads.

Erin started with one corner of a figure located at (-4,5) and translated it to end at (6,8). To find out how far the shape moved horizontally, she decided to find the difference between the two x-coordinates. she wrote: 6-(-4)
When Erin simplified 6-(-4) she got 2 as her answer. is this correct. If not, what is the correct simplification.
