Final answer:
The correct algebraic expression representing the sum of five times a number and seven being equal to twelve is A) 5n + 7 = 12.
Step-by-step explanation:
The question you are asking is a mathematical problem in which we need to find an algebraic expression that represents the given situation. The correct expression for the sum of five times a number and seven being equal to twelve is A) 5n + 7 = 12.
Let's break down the expression:
- 5n represents 'five times a number', where 'n' is the variable standing for the number.
- + 7 indicates that seven is being added to the product of five and the number (5n).
- = 12 demonstrates that the sum of 5n and 7 is twelve.
So, the correct answer which represents the sum as a mathematical expression is A) 5n + 7 = 12.
