Explain how to write and evaluate an algebraic expression.one more than the product of a number and seven, decreased by five; evaluate when n = 6

Answer:

To write the expression, start by identifying keywords: "product" indicates multiplication (7n), "one more than" indicates addition (+ 1), and "decreased by" indicates subtraction (- 5). This result in the expression 1 + 7n - 5. To evaluate, substitute 6 for n: 1 + 7(6) - 5. Using the order of operations, multiply seven and six to get 42. Then, add one to get 43, and subtract five to get a final value of 38.
