Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds. Which system of equations could be used to find the weight of each animal?

C

Step-by-step explanation:

First let’s identify that:

y = the kitten

x = the cat

Part 1 : The kitten weighs 3 pounds less than half the weight of Callie's cat.

We know that the kitten is half the size of the cat, which means the equation now looks like this:

x = y

But we also know that the kitten is 3 less than that equation, so now the equation is:

x = y -3

Part 2: Together the cat and the kitten weigh 18 pounds

Now, we have to use the other statement:

y + x = 18

But, that’s not one of the options, so we have to switch the x around and make it negative.

y = -x + 18

These are your answers!

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.
