like i dont get it at all wat so ever

anonymous · Answer

for the 3rd ques here it is
p+3r/6

anonymous · Answer

in all of your problems you should isolate the variable you're looking for,ie put it on one side of the equation

anonymous · Answer

ok

anonymous · Answer

do u want to try? or just thge answers?

anonymous · Answer

sure

anonymous · Answer

i still dont get it :(

swissgirl · Answer

ok ill show u one example and lets see if you can do the rest on ur own

anonymous · Answer

ok thank you

swissgirl · Answer

$ S=4v^2 $

swissgirl · Answer

So we gotta solve for V we must get V on one side of the equation by itself that is called isolating
So we need to first get rid of that 4 and in order to do that we divide that side by 4 but we know the rule that whatever we do to one side we gotta do to the other side> so we will divide both sides by 4
$ \large{S \over 4} = {4v^2 \over 4} $

$ \large {S \over 4}={4 \over 4}*v^2 $

$ \large {S \over 4}=v^2 $
Did u follow this far?

swissgirl · Answer

I added one step in the middle and separated the ${4 \over 4} $
Just to show u how i got rid of the 4

oh

anonymous · Answer

no i never got that far
