Final answer:
To solve the equation 5 + 3n = 29, subtract 5 from both sides and then divide both sides by 3 to find that the number of miles traveled on this taxi ride is 8.
Step-by-step explanation:
To solve the equation, we need to isolate the variable n. To do this, we can start by subtracting 5 from both sides of the equation: 3n = 24. Next, we can divide both sides of the equation by 3 to solve for n: n = 8. Therefore, the number of miles traveled on this taxi ride is 8.
