m +5=-2 -- 4

OpenStudy (anonymous):

are you looking for m? whats the dotted line and the 4???

OpenStudy (anonymous):

its a fraction

OpenStudy (anonymous):

k then you need to do the same on btoh sides to get rid of the fraction you times both sides by4 making it m+5=-2x4 which is -8

OpenStudy (anonymous):

then you -5 from both sides so it makes m=-8-5 which then makes-13

OpenStudy (anonymous):

so m=-13

OpenStudy (anonymous):

ooo ok thx

OpenStudy (anonymous):

5a+4a=-72

OpenStudy (anonymous):

5+4=9 so its 9a=-72

OpenStudy (anonymous):

then to get a you divide -72 by 9 so a=-8

OpenStudy (anonymous):

so when theres 2 letters in the equation u just add them twoogether then combine ur answer to divide it by the other number anthts how u get ur answer

OpenStudy (anonymous):

it depends of whther theyre in the same form if one is a an the other b you cant add them or if one of them are squared then you cant add them either

OpenStudy (anonymous):

but with your case you could :)

OpenStudy (anonymous):

understand>?

OpenStudy (anonymous):

oo ok now itke sence thx :) ur really smart...can u help me on some more problems but they arnt all the same subject some r porportions solving equations and other problems ??

OpenStudy (anonymous):

well i can always try right :) and i can tell you im not smart, i think i might just be older (so its basic stuff as i did it a while ago)

OpenStudy (anonymous):

ooo well yeah then tht also makes sence ...and yay thx !!

OpenStudy (anonymous):

ru gonna post ur qs??? cause i kinda need to go in a few mins :S

OpenStudy (anonymous):

(-35)2/5

OpenStudy (anonymous):

(-7/-6)(3/-4)

OpenStudy (anonymous):

is there a xbetween (-35) and 2/5?? and same for the other one?? is there a x between the two bracketS?

OpenStudy (anonymous):

one half the cube of a number x ??...

OpenStudy (anonymous):

no there isnt ...for neither ...

OpenStudy (anonymous):

im not really sure then :S post it as a qs by i think the answers should be: -14 and -7/8 for the other post it as a question and see what other put really sorrry :S

OpenStudy (anonymous):

u have to simplify using the rules for positive and negative #'s

OpenStudy (anonymous):

sorry im not sure post it as a question, im sure people will answer

OpenStudy (anonymous):

sorry but i need to go good luck completing all ur qs :)

OpenStudy (anonymous):

oooo ok then

OpenStudy (anonymous):

r u good at solving porportions ??

OpenStudy (anonymous):

x/9=24/3

OpenStudy (anonymous):

your looking for x??? well what i did is 24/3x3=72/9 so its x/9=72/9 x=72??? im not sure cause in maths i never remember words, i.e. proportions???
