Multiple Choice

    12am = 4

• a = 4 -12m

• a = 12m − 4

• $$a=\frac{1}{3m}$$

• $$a=\frac{12m}{4}$$

Multiple Choice

Solve for t.
D= rt

• $$\frac{D}{r}=t$$

• $$\frac{D}{t}=r$$

• Dr=t

• Dt =r

Multiple Choice

Solve -2 = 4r + s for s.

• s = -2 + 4r

• s = -2 - 4r

• s = 2 - 4r

• s = 2 + 4r

Multiple Choice

Solve for x: u = 2x - 2

Hint: u = 2(x-1)

(think distributive properties)

• x = u−1

• x = $$\frac{2}{u}+2$$

• $$x=\frac{u}{2}+1$$

• x= $$\frac{u-2}{2}$$

Reorder

Reorder the following: Given ax−b=c, solve for x.   

• add b to both sides

• ax = c+b

• Divide both sides by a

• $$\frac{ax}{a}=\frac{c+b}{a}$$

• $$x=\frac{c+b}{a}$$

Multiple Choice

Given V=lwh, solve for l.

• $$l=\frac{Vw}{h}$$

• $$l=\frac{V}{wh}$$

• $$l=\frac{wh}{V}$$

Multiple Choice

given the equation 8x + 4y= 15,

What is the first step in solving for y?

• Subtract 8x from both sides

• subtract 4y from both sides

• subtract 15 from both sides

• divide both sides by 4
