How do you convert miles per hour to distance traveled in 90 minutes?

• distance = speed × time = 90x

• distance = speed × time = 1.5x

• distance = speed × time = 2x

• distance = speed × time = 0.5x

What does it mean to solve an equation?

• To find the value(s) of the variable(s) that make the equation true.

• To simplify the equation to its lowest terms.

• To graph the equation on a coordinate plane.

• To determine the number of solutions an equation can have.

What is a factor in mathematics?

• A number that is always greater than one.

• A number or algebraic expression that divides another number or expression evenly.

• A term used to describe the sum of two numbers.

• A mathematical operation that combines two numbers.

What is the relationship between the length and width of a rectangle if the length is 3 less than twice the width?

• l = 2w - 3

• l = 3w - 2

• l = w + 3

• l = 2w + 3

What is a factor of the quadratic expression @@x^2 - 12x + 11@@?

• (x - 11)

• (x - 1)

• (x - 12)

• (x + 11)

What is the significance of the width in a rectangle?

• The width is the only dimension that determines the size of the rectangle.

• The width is one of the two dimensions that determine the size of the rectangle, along with the length.

• The width has no significance in determining the size of the rectangle.

• The width is always equal to the length in a rectangle.

How do you solve the equation @@3 + \sqrt{2x - 3} = 8@@?

• Isolate the square root: @@\sqrt{2x - 3} = 5@@, then square both sides: @@2x - 3 = 25@@, leading to @@x = 14@@.

• Subtract 3 from both sides: @@\sqrt{2x - 3} = 5@@, then square both sides: @@2x - 3 = 25@@, leading to @@x = 10@@.

• Add 3 to both sides: @@\sqrt{2x - 3} = 5@@, then square both sides: @@2x - 3 = 20@@, leading to @@x = 12@@.

• Multiply both sides by 2: @@\sqrt{2x - 3} = 10@@, then square both sides: @@2x - 3 = 100@@, leading to @@x = 51@@.

How do you find the area of a rectangle?

• A = l + w

• A = l × w

• A = 2(l + w)

• A = l - w

What does it mean for two quantities to be proportional?

• They are equal to each other.

• They maintain a constant ratio to each other.

• They can be added together.

• They are always integers.

What is the difference between area and perimeter?

• Area measures the space inside a shape, while perimeter measures the distance around a shape.

• Area is the distance around a shape, while perimeter measures the space inside a shape.

• Area and perimeter are the same measurements for any shape.

• Area is always larger than perimeter for any given shape.
