All its asking you to do is get b by itself
anonymous
  • anonymous
to do that you first want to subtract lw from both sides you get. A-lw=.5bh
anonymous
  • anonymous
then you dived both sides by .5h that leaves you with b=a-lw/.5h

ok well in order to move a variable to the other side you have to use the opposite sign
anonymous
  • anonymous
so you would subtract
anonymous
  • anonymous
A = lw + 0.5bh to get lw to the other side you subtract lw to both sides that get read of it one one side so know you have a-lw=.5bh
anonymous
  • anonymous
since you are multiplying .5bh the opposite sign would be division. so divide .5h from both sides because you need b all by itself on one side
anonymous
  • anonymous
that leaves you with a-lw/.5h=b do you get it now?
anonymous
  • anonymous
kind of i think
anonymous
  • anonymous
so what do you not get so i can explain it some more?
anonymous
  • anonymous
so my answer is b = A divided by the quantity l times w plus 0.5 times h
anonymous
  • anonymous
almost instead of plus 0.5 time h it would be divided by 0.5 times h
anonymous
  • anonymous
so its b = The quantity A minus l times w all divided by 0.5 times h
anonymous
  • anonymous
yes you got it
