Aiden wanted to model -15 + 15 = 0 on the number line. he first drew an arrow 15 units long starting from zero that pointed to the left. he then draws another arrow 15 units long starting from zero that points to the right. what error did aiden make?

Aiden needed to go 15 units to the right from -15 and end at 0

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.

86
