To model the problem containing an unknown number, translate the statement into an equation.Sixteen is five less than a number. Which steps would you take to translate the statement?
Answer
A
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n.
B
Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.
C
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = n – 5.
D
Replace “is” with =, “less than” with ÷, and “a number” with n to get 16 = 5 ÷ n.
Explanation
“Is” means equals, and “a number” can be represented by n. The phrase “five less than a number” means subtract 5 from the number, giving n − 5. So the equation is 16 = n − 5, which is choice C.
