Answer 2

The equation in question is:

40w + 12.50 = 492.50

This equation suggests that Nicole has a certain cost per week for self-defense classes (represented by 40w, where w is the number of weeks), plus a one-time fee (represented by 12.50). The total amount paid is represented by 492.50.

The situation best represented by this equation is:

D) Nicole paid $492.50 for self-defense classes. She paid a $12.50 registration fee and $40 for each week she was enrolled in the classes. What is w, the number of weeks Nicole was enrolled in self-defense classes?

This option correctly matches the cost per week (40w), the one-time registration fee (12.50), and the total amount paid (492.50) as given in the equation. To find out the number of weeks (w) that Nicole was enrolled, we would solve the equation.

Answer 3

The first operation used in solving the equation 2x + 5 = 10 is subtraction. You would start by subtracting 5 from both sides of the equation to isolate the term with the variable (2x) on one side.

So the correct response is:

D) subtraction
