Question

Fill in the missing number

84/6- Missing Number x 3 =11

Answer 1

84/6-m.3=11

84/6-11=3m

18/6=3m

3=3m

1=m

m:missing number

Answer 2

is the 1st equation m*3?

Answer 3

yep

Answer 4

84/6-Missing Number x 3 =11

Answer 5

was three multiplied to m or is it multiplied to the fraction??

Answer 6

Answer 7

yes

Answer 8

@Selena2345, I thought you said you understood after the last problem which was exactly the same. Were you being less than honest?

Answer 9

if it is multiplied to the fraction, it's like this:

(84/6-m) (3) = 11

then, divide 3 from both sides(the same as mutiplying 1/3 to both sides)

\[\frac{ 1 }{3 } \left( \frac{ 84 }{ 6-m} \right)\left( 3 \right) = \frac{ 1 }{ 3 } \left( 11 \right)\]

so, it'll be like this
\[\frac{ 84 }{ 6-m } = \frac{ 11 }{ 3 }\]

cross multiply
(6-m)(11) = (84)(3)
66 - 11m = 252
-11m = 252 - 66
-11m = 186
\[\frac{ -11m }{ -11 } = \frac{ 186 }{ -11 }\]

Answer 10

don't know if it's righ... t try checking it..
\[m = \frac{-186? }{ 11 }\]

Answer 11

thank you so much your the best

Answer 12

@calculusfunctions Is my solution right?? i kinda doubt my answers..

Answer 13

your answer is very good and smart

Answer 14

thanks..

Answer 15

your welcome

Answer 16

@darkprince, your first answer of m = 1 is perfect! Your second answer however, is incorrect. The question is\[\frac{ 84 }{ 6 }-3m =11\]Therefore as I said, your first response was perfect!

Answer 17

sorry..i got the wrong picture..

if you simplified the fraction, you'll get
14-3m = 11
14 - 11 = 3m
3 =3m
1 = m
