Understanding One-Step Equations

This video tutorial covers solving three application problems using one-step equations involving multiplication or division. The first example calculates the cost of one pound of strawberries by dividing the total cost by the number of pounds. The second example determines Marcella's car payment by dividing Ramon's payment by three. The final example finds Charlotte's age by multiplying David's age by four, demonstrating the use of fractions in equations.

What is the first step in solving a one-step equation involving multiplication?

• Add the same number to both sides

• Subtract the same number from both sides

• Multiply both sides by the same number

• Divide both sides by the same number

If Devin bought 5 pounds of strawberries for $9.45, what is the cost of one pound?

• $2.00

• $1.99

• $1.95

• $1.89

In the context of the video, what does the variable 'c' represent in the first example?

• Total cost of strawberries

• Total weight of strawberries

• Number of pounds of strawberries

• Cost of one pound of strawberries

What operation is used to solve the equation 5c = 9.45?

• Addition

• Multiplication

• Subtraction

• Division

Ramon's car payment is three times Marcella's. If Ramon's payment is $462, what is Marcella's payment?

• $160

• $154

• $164

• $150

What equation represents the relationship between Ramon's and Marcella's car payments?

• r = m / 3

• r = m - 3

• r = 3m

• r = m + 3

David is 12 years old and is one-fourth as old as Charlotte. How old is Charlotte?

• 36

• 42

• 48

• 50

What is the reciprocal of 1/4?

• 2

• 4

• 1/4

• 1/2

What is the first step in solving the equation 12 = 1/4c?

• Divide both sides by 4

• Multiply both sides by 4

• Subtract 4 from both sides

• Add 4 to both sides

What is the main concept demonstrated in the video?

• Solving multi-step equations

• Solving one-step equations

• Graphing linear equations

• Factoring polynomials
