Multiple Choice

Solve for the variable.

$$4x=24$$

• $$x=6$$

• $$x=24$$

• $$x=4$$

• $$No\ solution$$

Multiple Choice

x - 62 = 123

How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

Multiple Choice

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

Multiple Choice

A rectangular garden sits next to a house. There is fencing on three sides of the garden and the fourth side is the house. There is a total of 21.5 meters of fencing around the garden. The length of the garden along the house is 9 meters. Which equation can be used to find the width, w, of the garden in meters?

• $$2w+9=21.5$$

• $$2w+18=21.5$$

• $$2w-21.5=9$$

• $$2w+21.5=9$$

Multiple Choice

Demarco has a piece of fabric 6 yd long. He uses a piece 3 yd long. He cuts the rest into strips that are each $$\frac{3}{4}$$ yd long. Which equation can be used to find how many $$\frac{3}{4}$$ yd long strips are there?

• $$6x\ +\frac{3}{4}x=3$$

• $$3x+\frac{3}{4}=6$$

• $$3+\frac{3}{4}x=6$$

• $$6-\frac{3}{4}x=3$$
