SOLVE. (QUICKLY PLEASE, WILL FAN AND LIKE) http://imgur.com/CF4CHB1

OpenStudy (ninjaslice):

I will solve for you, one moment.

OpenStudy (anonymous):

B

OpenStudy (anonymous):

X is less than or equal to 4

OpenStudy (ihelpyoulearn):

I agree with @Harlequinn1109 its B

OpenStudy (anonymous):

It would be x is greater than or equal to four

OpenStudy (ninjaslice):

It is D due to when you divide and change a number from Negative to Positive it changes, It would be D.

OpenStudy (jokersmart):

Oh, so B or D? o.o

OpenStudy (anonymous):

D

OpenStudy (anonymous):

It also changes the direction of the inequality sign. So the answer is C.

OpenStudy (anonymous):

I forgot to change the sign

OpenStudy (jokersmart):

Ok, I'm just gonna go with D. xD

OpenStudy (ninjaslice):

:D yep! good choice @JokerSmart

OpenStudy (anonymous):

You will get it wrong. @JokerSmart

OpenStudy (jokersmart):

Explain~

OpenStudy (jokersmart):

I have two people who clearly said D.

OpenStudy (anonymous):

Subtract 13 from both sides and you get \[-20\ge-5x\] Then divide by -5 and change the sign of the answer and switch the direction of the inequality.\[4lex\]

OpenStudy (anonymous):

\[4\le x\]

OpenStudy (ninjaslice):

It is D due to when you do the math: you do 13- (-7) = -20 then do -5 Into -20 Which then equals 4 when divided, then switch the sign to the right side DUE TO you just turned a negative number to a positive number.

OpenStudy (ninjaslice):

This is Simple Inequalities, any math teacher will tell you what I just did (go ask him.her ;) )

OpenStudy (anonymous):

it is just simply -7-13

OpenStudy (anonymous):

so -20

OpenStudy (ninjaslice):

DIVIDED BY -5

OpenStudy (ninjaslice):

Which equals 4. and then SWITCH THE SIGN OVER

OpenStudy (anonymous):

I know it is simple but I have done these multiple times and I have learned it from a PH.D. in math.

OpenStudy (ninjaslice):

Better go get a new PHD no offence

OpenStudy (ninjaslice):

Also should use Youtube for this, really useful oh yeah, and www.google.com AND www.khanacademy.org/profile/ninjaslice LOOK AT MY SCORE. IM NOT DUMB.

OpenStudy (anonymous):

-20 is greater than -5x then you divide by -5 and switch the sign over so it points to the x.

OpenStudy (anonymous):

so x is greater than 4

OpenStudy (ninjaslice):

Dude, you so did not even do ALgebra, only someone who understands algebra would know this problem. even a 8th grader would not know this. so please, before you try to answer a question that you may not know.... please google it :)

OpenStudy (anonymous):

so x is greater than 4

OpenStudy (anonymous):

I did. −7≥13−5x Solve for x Answer Answer: Solve for x by simplifying both sides of the equation, then isolating the variable. x≥4

OpenStudy (anonymous):

I used mathway and my brain.

OpenStudy (ninjaslice):

Whatever dude, im just saying you are wrong, that's it. @JokerSmart I hope you answered with my Answer I gave you, hope it helps. I have Straight A's in algebra and I can proof it. and in geometry so....

OpenStudy (anonymous):

I do too... just saying

OpenStudy (ninjaslice):

banana, Dude, You are wrong just admit it, please go google it and realize you are wrong.

OpenStudy (anonymous):

Fine. And by the way I am not a dude.

OpenStudy (ninjaslice):

Awesome god bless

OpenStudy (ninjaslice):

oh btw, gamers can also call a girl dude :) just so you know. its another term. (and im a gamer so...) its respectful to put them on the same level.

OpenStudy (ninjaslice):

Guy or girl it does not matter gender.
