Rearranging Formulas/Literal Equations AMI #7

Solve for t.
D= rt

• D/r = t
• Dr = t
• D/t = r
• Dt = r

pV = nRT

solve for R

• $R=\frac{pV}{nT}$

• $R=\frac{p}{n}+\frac{V}{T}$

• $R=pV-nT$

• $R=\frac{(pV-n)}{T}$

Solve the literal equation for the given variable.

• $\frac{2A}{h}$

• $\frac{2}{h}$

• $2Ah$
  

• $\frac{Ah}{2}$
  

Solve:

 $V=πr²h$  , for h

•  $\frac{V}{πr²}=h$  

•  $V-πr²=h$  
  

•  $V+πr²=h$  

•  $\frac{V}{π}=h$  
  

Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

• s = -Dn + C
• s = Dn - C
• s = Dn/C

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

Which of the following are basic rules used for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the opposite operation

• 13

• 36

• -36
