This morning gwen found that the snow on the sidewalk was 5 and 3/8 inches deep. at lunch the snow was 2 and 7/8 inches deep at the same place. how many inches of snow had melted? use numberline to show work

2.75

step-by-step explanation:

5 and 3/8 inches = 5 + 3/8 =  5 + 0.625 = 5.625

2 and 7/8 inches =  2 + 7/8 = 2 + 0.875 = 2.875

the inches that snow melted: 5.625 - 2.875 = 2.750

i not know

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
