The video tutorial covers linear equations in disguise, following module 4, lesson 8 of the eighth-grade curriculum. It includes examples of solving linear equations with variables on both sides, using cross multiplication, and working with similar triangles to solve proportions. The tutorial also provides practice exercises to reinforce the concepts taught.

What is the requirement for an equation to be considered linear?

• The variable must be raised to the power of 2.

• The variable must be raised to the power of 0 or 1.

• The equation must have a constant term.

• The equation must have no variables.

How do you eliminate a fraction in a linear equation?

• Add the numerator to both sides.

• Subtract the denominator from both sides.

• Multiply both sides by the denominator.

• Divide both sides by the numerator.

What is the result of distributing 8 times (6 + x)?

• 6x + 8

• 14x

• 48x + 6

• 48 + 8x

Why are improper fractions often used in algebra?

• They simplify calculations.

• They are more accurate.

• They are easier to read.

• They are the standard form in algebra.

What does it mean when two triangles are similar?

• They have the same angle measurements.

• They have the same side lengths.

• They are identical in size.

• They have no proportional sides.

How do you set up a proportion for similar triangles?

• By comparing the angle measurements.

• By setting the ratios of corresponding sides equal.

• By adding the side lengths together.

• By equating the side lengths directly.

What is the first step in solving a linear equation with variables on both sides?

• Subtract the smaller variable from both sides.

• Multiply both sides by the same number.

• Divide both sides by the same number.

• Add the variables together.

What should you do if your answer is an improper fraction?

• Convert it to a mixed number.

• Multiply it by 10.

• Leave it as an improper fraction.

• Round it to the nearest whole number.

In the equation 7(5 + 2x) = 6(3x - 1), what is the first step to solve it?

• Subtract 2x from both sides.

• Divide both sides by 7.

• Add 5 to both sides.

• Distribute the 7 and 6.

What is the simplified form of x = 41/4?

• 41.4

• 10.25

• 10 1/4

• 41/4
