Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable. It typically involves addition or subtraction followed by multiplication or division.

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in reverse order: first, eliminate any constant added or subtracted from the variable, then divide or multiply to solve for the variable.

Front

What does the variable 'c' represent in the equation 4.1c - 0.75 = 4.12?

Back

In this equation, 'c' represents the cost of the fruit in dollars per pound.

Front

What is the first step to solve the equation 4.1c - 0.75 = 4.12?

Back

The first step is to add 0.75 to both sides of the equation to eliminate the constant from the left side.

Front

What is the total cost of the fruit before applying the coupon in the equation 4.1c - 0.75 = 4.12?

Back

The total cost before applying the coupon is $4.12 + $0.75 = $4.87.

Front

What is the formula to find the cost of each DVD in the equation 1 DVD = (total cost - shipping cost) / number of DVDs?

Back

The formula is: Cost of each DVD = (Total cost - Shipping cost) / Number of DVDs.

Front
