Solve 6n+1 >10 round to four decimal places ?

Question

a n>0.2851

b n>0.6667

c n>1.2851

d n>0.7782

Answer 1

the answers don't fit the question.

But, guessing maybe the answer *should be*

b)  n>0.6667

working backwards:

n>0.6667   [here I would multiply both side by 6 ]

6n > 4    [and add "1" to both sides ]

6n + 1 > 5  <====  *this* would yield answer "b"

or

6n +  6 > 10  <====  *this* would yield answer "b"

so maybe, if you typed it in wrong ...

oh I don't know, just a way to make sense of this question

good luck

Answer 2

Hrm, dunno...

I would assume you would just go:

6n+1 > 10

6n+1-1 > 10-1

6n > 9

n > 9/6

n > 1.5

...

Answer 3

6n + 1 > 10

     -  1> - 1

___________

6n      >   9

___        ___

6            6

n > 9/6

n=1.5000

Answer 4

6n + 1 > 10

-1 fr. both sides

6n > 9

divide both sides by 6

n > 1.5

Answer 5

6n + 1 > 10

6n > 10 - 1

6n > 9

n > 9/6

n > 1.5
