the sum of two numbers is 5. three times the larger number plus two times the smaller number is 28. find the numbers.
the larger number is
and the smaller number is
.
alan answer

Step-by-step explanation:

So let's make the two numbers "X" and "Y".

X + Y = 5

That's the very first line

let's take X as the bigger number and Y as the Smaller number.

3x + 2y = 28

now we have two equations and two unknowns.

We can also arrange the first equation to be as

X = 5 - Y

substitute this equation in the 2nd equation

3(5- Y) + 2Y = 28

15 - 3Y + 2Y = 28

-Y = 13

Y = -13

Substitute Value of Y in any equation to get X

X = 5 - (-13)

X = 18

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.
