Multiple Choice

What is the first step in solving this equation for b?

 $A\ =\ bh$  

• Subtract h from both sides.

• Divide by h on both sides.
  

• Add h to both sides.

• Multiply by h on both sides.

Multiple Choice

Solve for b. 

 $A\ =\ \frac{1}{2}bh$  

•  $\frac{2A}{h}$  

•  $2Ah$  

•  $\frac{2}{h}$  

•  $\frac{Ah}{2}$  

Multiple Choice

Solve for s.

 $2s=6t+8w$ 

•  $s=12t+16w$  

•  $s=6t+4w$  

•  $s=3t-4w$  

•  $s=3t+4w$  

Multiple Choice

Solve for F.

 $S=3F-24$  

•  $F=\frac{\left(s+24\right)}{3}$  

•  $F=3S+24$  

•  $F=\frac{S}{3}+24$  

•  $F=3\left(S+24\right)$  

Multiple Choice

Solve for x.

 $x+2w=m$  

•  $x=m-2w$  

•  $x=2mw$  

•  $x=0.5m-w$  

•  $x=\frac{m}{2w}$  

Multiple Choice

Solve for r.

 $C=2\pi r$  

•  $\frac{C}{2\pi}=r$  

•  $C\ +2\pi=r$  

•  $C-2\pi=r$  

•  $2\pi C=r$  

Multiple Choice

Solve for y.

 $8x+4y=16$  

•  $y=-8x+16$  

•  $y=-2x+4$  

•  $y=2x-4$  

•  $y=-8x+12$

You're almost done.

Multiple Choice

Solve for W.

 $A=LW$  

•  $A=\frac{L}{W}$  

•  $W=A$  

•  $W=\frac{L}{A}$  

•  $W=\frac{A}{L}$
