Algebra Problem Help..PLZ and thnks :)?

Question

Solve each equation for the indicated variable

1) I=Prt, solve for r

2) A=bh/2, solve for h

3) Ax+by=c, solve for y

4) I=V/R, solve for V

#

Answer 1

1. r = I/(Pt)             Divide both sides by Pt

2. h = 2A/b            Multiple both sides by 2, then divide both sides by b

3. y =( c - Ax)/b     Subtract Ax on both sides, then divide both sides by b

4. V = IR               Multiply both sides by R

Hope this helps.

Answer 2

r = (I/P)/t  

h = (2A)/b

y = (c-Ax)/b

V= IR

haven't done this for a while, but it might help. Good luck.

Answer 3

1)   I=Prt

I/(Pt)=r

2)  A=bh/2

   2A=bh

2A/b=h

3)Ax+By=C

         By=C-Ax

           y=(C-Ax)/B

4) I=V/R

  IR=V

    

Answer 4

There is a reason you have teachers.

Answer 5

1) I/Pt=r

2) 2A/b=h

3) c-Ax/b=y

4) IR=V
