1. To translate the phrase "the difference of a number and sixteen" into an algebraic expression, we need to identify the variable representing the number. Let's say the variable is 'n'. The word "difference" in this context usually means subtraction. Therefore, the algebraic expression would be B. n - 16.
2. To translate the phrase "five times k" into an algebraic expression, we need to represent the variable 'k' multiplied by five. The word "times" implies multiplication. Therefore, the algebraic expression would be A. 5k.
3. To evaluate the expression 3(3t + s) when s = 9 and t = 12, we substitute the given values into the algebraic expression and simplify.
So, 3(3t + s) becomes 3(3*12 + 9) = 3(36 + 9) = 3(45) = 135.
Therefore, the answer is D. 135.
4. Similarly, to evaluate the expression 2s - t when s = 9 and t = 12, we substitute the values into the algebraic expression and simplify.
So, 2s - t becomes 2*9 - 12 = 18 - 12 = 6.
Therefore, the answer is B. 6.
