Learn how to apply the cross product to solve the proportion ex 10, (x - 5)/4 = 3/2

The video tutorial demonstrates how to solve a reinforcement problem using the cross product method. It begins with an introduction to the concept, followed by a detailed explanation of multiplication and the importance of using parentheses. The tutorial then applies the distributive property to solve the equation, providing step-by-step guidance. The process concludes with solving the equation and verifying the solution.

What is the first step in applying the cross product to solve a proportion?

• Add the numbers on both sides.

• Multiply the numbers diagonally.

• Subtract the smaller number from the larger one.

• Divide the numbers by each other.

Why is it important to use parentheses when multiplying a number with an expression?

• To ensure the expression is added correctly.

• To avoid confusion with subtraction.

• To correctly apply the distributive property.

• To make the expression look neat.

What property is applied after using parentheses in multiplication?

• Commutative Property

• Distributive Property

• Associative Property

• Identity Property

What operation is performed after applying the distributive property to isolate the variable?

• Division

• Multiplication

• Subtraction

• Addition

What is the final step to find the value of the variable in the equation?

• Multiply both sides by 2.

• Divide both sides by 2.

• Subtract 10 from both sides.

• Add 5 to both sides.
