Question 17260: help.... I cant find the answer.
G= .067+.052 Log (M)
I tried subtracting .067 from both sides and got
G-.067 = .052 Log (M)
then dividing both sides by .052
to get (G-.067)/.052=Log M
then plugged it into my calculator and got the wrong answer.

Are you solving for M? If so, you are correct so far. I think you might want to do two more steps. Rirst, the clear those decimals, multiply both numerator and denominator by 1000. That might look nicer:
%28G-.067%29%2F.052=log%2810%2CM%29
+%281000G-67%29%2F52=log%2810%2CM%29+

Next,suing the basic definition of logarithms: +log%2810%2CM%29=+Y means 10%5EY=M
10%5E%28%281000G-67%29%2F52%29+=+M++

As an alternative, if you did NOT multiply numerator and denominator by 1000, you would get this:
10%5E%28%28G-.067%29%2F.052%29+=+M++


These answers should be the same. Do either of these look right?
