Answer:
Step-by-step explanation:
Let n represent the unknown number.
1) The sum of a number and 5 is less than 7 becomes n + 5 < 7
2) The product of a number and 8 is at least 25 becomes 8n ≥ 25
3) Six less than a number is greater than 54 becomes n - 6 > 54
4) the quotient of a number and 12 is no more than 6 becomes n/12 ≤ 6
