Four more than three times a number n is 19. Which equation represents this?
- A. 3n + 4 = 19Correct
- B. 3(n + 4) = 19
- C. 4n + 3 = 19
- D. 3n − 4 = 19
Answer: A. 3n + 4 = 19
'Three times a number' is 3n; 'four more than' that is 3n + 4.
Why the other answers are wrong
- B. 3(n + 4) = 19
- 3(n + 4) is three times 'four more than n', a different phrase.
- C. 4n + 3 = 19
- Swaps the roles of 3 and 4.
- D. 3n − 4 = 19
- 'More than' means add, not subtract.
