Answer 7

12 x = 30

here , 'x' is MULTIPLIED by 12.
so to isolate 'x' , we do the inverse operation of DIVIDING everything by 12

so, what u get when you divide both sides by 12 in 12x=30 ?

Answer 8

To answer that you divided 4 on 2 to find x .
k ?!:)
So in there do this work !:)

Answer 9

144 & 360

Answer 10

What ???

Answer 11

you got 144 and 360 by MULTIPLYING by 12
, you need to DIVIDE by 12 actually

Answer 12

uhh have you learned that rule about what you do to one side you have to do to the other?

Answer 13

I missed type something hold on. Its 12x=60 not 30 oh my gosh i am so sorry!

Answer 14

same thing

Answer 15

doesn't matter
still you divide by 12 on both sides of
12x=60

Answer 16

1 & 5

Answer 17

correct!
so, 1x = 5
so, x= 5
got this ?

Answer 18

He gets it. he asked so would it be 5 or 1/5??

Answer 19

lets verify it too
left side = 12 x = 12*5 = 60 = right side
so yeah, x=5

Answer 20

in hope of attracting more buyers a printer company decides to cut all its prices by half. if the new price of a printer is %54 how much did the printer cost before the change in price??

$20
$27
$54.50
$108.00 ***

Answer 21

let old price be $x
new price = 1/2 of old price = (1/2) * 54
got this ?

Answer 22

got it.

Answer 23

so what will be new price ?

Answer 24

27

Answer 25

oops i made an error,
new price = 54
so, 54 = (1/2)x
now find x
and it not 27...

Answer 26

he said would be it A?

Answer 27

no..
see, prices cut by half means
new prices = (1/2) * old prices
new price = 54 is given
we need old price =x
so, 54 = (1/2)x

multiply 2 on both sides, what u get ?

Answer 28

I think hes just guessing because hes getting tired of doing algebra LOL!!

Answer 29

108 & 1

Answer 30

yes,
so, x =108 :)

if he is tired, he can do some part of homework later...

Answer 31

Hes homeschooled and once he starts it he cant finish. so there is one more question.
So answer would be 108 he said?

Answer 32

yes, 108 is correct answer.
post the next Question :)

Answer 33

the solution x=6 is a solution to which of the following equations??

-5x=1

3=18x

-4x=-20

60=10x

Answer 34

take each choice, one by on
1) -5x =1

left side = -5x = -5(6) = -30
right side = 1
so left side \(\large \ne\)right side
so its not the first choice,
got this ?

Answer 35

\(\ne\) means not equal to

Answer 36
