Justin is 3 years older then Sam, and Justin’s age in 2 years will be twice what Sam’s age was 3 years ago. Find their present ages.

Present age of Justin=14

Present age of Sam=11

Step-by-step explanation:

Let the present age of Sam=x

Given that Justin is 3 years older than Sam

present age of Justin=x+3

Age of Sam 3 years ago=x-3

Age of Justin two years hence=x+3+2=x+5

given that after 2 years Justin's age will be twice that of Sam's age three years ago

therefore

Present age of Sam=x=11

Present age of Justin=x+3=11+3=14

step-by-step explanation:

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.
