Question

If y varies jointly as x and z, and y = 33 when x = 9 and z = 12, find y when x = 16 and z = 22.

Answer 1

@PatrickJordon work it out step by step I want to see it

Answer 2

Oh great thnx -_-

Answer 3

mmhhmm now start typing
I'll start you off
Y=KXZ

Answer 4

ugh.

Answer 5

what you doing you started perfect

Answer 6

then got a big number 325, then what = WRONG

Answer 7

okay type the equation i gave you

Answer 8

Y=KXZ

Answer 9

Well we do know y F***

Answer 10

what variables do you know substitute them in the EXACT place they are

Answer 11

33=K*16*22

Answer 12

good know what do you do

Answer 13

*now

Answer 14

(16(22)=352
K=352

Answer 15

33= 352*16*22

Answer 16

do not mess with 33 so lets start over from the beginning
33=k(9)(12)

Answer 17

-_-

Answer 18

come on you can do it.

Answer 19

33=108*9*12
Doubtful

Answer 20

no you got 33=108 perfect but you keep forgetting the variable K.

Answer 21

Ehm, isnt 108 k

Answer 22

no its x and z combined so 108 is xz not k

Answer 23

so Divide 108 by 33

Answer 24

To get, "k"

Answer 25

perfect yes but first let me see you equation now that you know that 108 it is xz

Answer 26

33=k(108xz)

Answer 27

make sure your answer is a fraction once you have divided

Answer 28

33=108k that is what your equation should look like

Answer 29

\[\frac{ 36 }{ 11 }\]

Answer 30

other way around

Answer 31

\[\frac{ 11 }{ 36 }\]

Answer 32

perfect so know that we know what k is we fill it in as y= \[y=\frac{ 11 }{ 36 }xz\]what do you do next to get y

Answer 33

you get rid of xz dunno

Answer 34

no it starts with sub

Answer 35

Substitution :/

Answer 36

Subtract
Subway

Answer 37

the first one substitute the variables x and z with 9 and 12

Answer 38

Ughhh.

Answer 39

come on you almost done

Answer 40

"Almost"

Answer 41

this is your last step if you follow the directions i just gave youthen multiply the all up and that is your Y

Answer 42

just 108,, dunno :/

Answer 43

okay \[y=\frac{ 11 }{ 36 }*16*12\] you should get a fraction

Answer 44

and what does Subway have to do with math

Answer 45

i was trying to be funny :P

Answer 46

lol

Answer 47

\[\frac{ 176 }{ 3 }\] How the H

Answer 48
