Solve each formula for the indicated variable or constant:
1.) C= 5/9(F-32), for F
C=5(F-32)/9
9C=5F-160
5F=9C+160
F=(9/5)C+32
..
2.) I= prt , for t
t=I/pr
..
3.) A= h/2(b1+b2), for b2
A=h(b1+b2)/2
2A=hb1+hb2
hb2=2A-hb1
b2=(2A-hb1)/h
..

4.) A= P(1+r/n)^nt,for P
P=A/(1+r/n)^nt
..
5.) A= P(1+r/n)^nt, for t
A/P=(1+r/n)^nt
take log of both sides
log(A/P)=ntlog(1+r/n)
t=log(A/P)/nlog(1+r/n)
