Help please? Translate the sentence into an inequality. Seven times the sum of a number and 30 is at most 23 Use the variable c for the unknown number.

OpenStudy (gabebae):

7c+30=23

OpenStudy (gabebae):

hold on it said at most

OpenStudy (gabebae):

7c+30 is less than or equal to 23

OpenStudy (anonymous):

??? @GabeBae

OpenStudy (gabebae):

I'm sorry?

OpenStudy (anonymous):

:( it's sooooo confusing... I've been getting them all wrong but could swear they are right

OpenStudy (gabebae):

It must be 6(x+30) is less than or equal to 23

OpenStudy (gabebae):

Sorry c instead of x

OpenStudy (anonymous):

7(c+30) less than or equal to 23?

OpenStudy (gabebae):

oh sorry yes

OpenStudy (anonymous):

That was correct!

OpenStudy (gabebae):

I've been switching pages and got confused

OpenStudy (gabebae):

I'm sorry about misunderstanding it earlier

OpenStudy (gabebae):

I hope that didn't mess up your score or anything

OpenStudy (anonymous):

What about this one??? The difference of twice a number and 6 is at least 27

OpenStudy (anonymous):

No! Thank you, i really appreciate it. At least now I understand lol

OpenStudy (gabebae):

2(c+6) is less than or equal to 27

OpenStudy (gabebae):

waiit don't submit

OpenStudy (gabebae):

It asks for the difference

OpenStudy (gabebae):

2(c-6)

OpenStudy (anonymous):

so it's 2(c-6) less than/equal to 27

OpenStudy (anonymous):

So the correct answer was 2x-6 greater than or equal to 27

OpenStudy (gabebae):

oh? I remember doing this in algebra 1
