A rectangular flag has an area of 3/8 of a square foot. The length is 3/4 of a foot. What is the width of the flag?

• 1/8 foot

• 1/4 foot

• 1/3 foot

Use the information given to answer the question. A customer spends $41.94 on 6 pairs of flip-flops that all cost c dollars per pair. Which equation represents the scenario correctly?

• c + 6 = 41.94

• c + 41.94 = 6

• 6c = 41.94

• 41.94c = 6

Answer explanation

The variable c stands for cost per pair of flip-flops. The customer bought 6 pairs for $41.94. The number of pairs of flip-flops (6) multiplied by their cost per pair equals the total spent of $41.94.

Which statement about the expression 13y - 3y - y is true?

• It is always equivalent to 9y because when you combine the like terms, you get 9y.

• It is always equivalent to 10y because when you combine the like terms, you get 10y.

• It is always equivalent to 16y because when you add the coefficients, you get 16y.

• It is always equivalent to 17y because when you add the coefficients, you get 17y.

Answer explanation

When you see a variable without a number in front of it, there is an implied 1 there.

Therefore, 13y - 3y - 1y = 9y.

The point (-16, 3) is plotted on a coordinate plane. Which point represents (-16, 3)

reflected across the y-axis?

• (16, -3)

• (3, -16)

• (-16, -3)

• (16, 3)

Answer explanation

Keep the coordinate of the axis you are reflecting across, find the opposite of the other coordinate.

The first coordinate is always the x axis, and the second is always the y.
