Answer 3

4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.
Hope I helped!

Answer 4

?

Answer 5

what are u people talk about i want my medal now

Answer 6

where does the 20 come from?

Answer 7

I don't understand this

Answer 8

me neither

Answer 9

ok i got this from yahoo answers they gave the guy as best response

Answer 10

He just wants someone 2 give him a medal

Answer 11

as far as i can see, he could have made \(57\div 3=19\) three legged stools

Answer 12

LIES what is that garbage

Answer 13

there is no other condition for this problem
it does not say how many pieces of furniture were made
it only asks, "if he made 57 legs, how many 3 legged stools could he have made?" and the answer is, if he made all stools, there would by 19 of them

Answer 14

@UsArmy3947 you got to read the question before you google, and read the answer once you have found something to see if it makes sense

Answer 15

there is no 19

Answer 16

57 is not divisible by 3?!

Answer 17

these are the answer choices
A.
8

B.
9

C.
10

D.
11

Answer 18

hey who deleted that?

Answer 19

then there is something missing in the question

Answer 20

A carpenter makes legs for 3-legged stools and 4-legged tables. He makes a total of 57 legs.

He could have made legs for how many 3-legged stools?

Answer 21

Ops, sorry.

Let number of the 3-legged thing is x and 4-legged thing is y.

leg numbers: 3*x+4*y = 57

So we are looking for the maximum value of x. Try this:
57 divisible by 3 but he made legs for both 3-legged and 4-legged things so he cant use all of this for 3-legged thing, so subtract 4, it is 53
53 is not divisible by 3, so subtract 4, it is 49
49 is not divisible by 3, su subtract 4, it is 45
45 is divisible by 3 and it is 15. He can make 15 3-legged something.

Answer 22

That is correct answer, i think

Answer 23

is this the entire question
A carpenter makes legs for 3-legged stools and 4-legged tables. He makes a total of 57 legs. ?

Answer 24

yes

Answer 25

A carpenter makes legs for 3-legged stools and 4-legged tables. He makes a total of 57 legs.

He could have made legs for how many 3-legged stools?

A.
8

B.
9

C.
10

D.
11

Answer 26

then something is missing
maybe the total number of pieces he made

Answer 27

I think

Answer 28

oooh i see maybe what it is asking, it is giving you choices and you have to pick the one that is possible!

Answer 29

ok lets try 8
if he made 8 stools then he made \(3\times 8=24\) legs for stools
that leaves \(57-24=33\) legs for tables

Answer 30

but that cannot be right because the number of legs for tables must be divisible by 4

Answer 31

UsArmy! Who is ur gf?

Answer 32

and 33 is not
lets try again with the next number

Answer 33

ok

Answer 34

\(9\times 3=27\) and \(57-27=30\) but 4 does not go in to 30 evenly so that one is out too

Answer 35

ok

Answer 36

hey who is the punk that keeps deleting it?

Answer 37

10 does not work either because \(3\times 10=30\) and \(57-30=27\)
four does not go in to 27

Answer 38

show ur face u coward

Answer 39

i bet he is in here

Answer 40

and finally we try 11

Answer 41

oh so it's 11?

Answer 42

\(3\times 11=33\) and \(57-33=24\) which IS divisible by 4
so it is 11

Answer 43

hey now the punk gave me a warning

Answer 44

oh ok thanks.

Answer 45

if hes here lets go to chat

Answer 46

Yay it's11 I told u Satellite73
lol

Answer 47

we needed to understand the question
without the answer choices it did not make much sense

Answer 48

I got it correct. thanks

Answer 49

yw

Answer 50

lol satellite u delete it
