Hillview Elementary School has 3 sixth-grade classes of 22 students each. On a Friday, the entire 6th grade went on a field trip to the science museum. Some of the 6th graders were absent that day. If s represents the number of 6th grade students who were absent on that Friday, which of the following expressions shows how many 6th graders went to the science museum?

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.

add 8+12 to get a simplified answer of 12r-20

the answer to 3p+12m+8=23pm
