Final answer:
The expression '5 less than 3.1 times a number n four more than the quotient of 12 and a number x' is equal to 3.1n - 5 + (12 / x) + 4.
Step-by-step explanation:
To find the expression '5 less than 3.1 times a number n four more than the quotient of 12 and a number x', we can break it down into smaller parts and assign variables to each part. Let's define n as the number and x as the other number. Then the expression can be written as:
3.1n - 5 + (12 / x) + 4
So, '5 less than 3.1 times a number n four more than the quotient of 12 and a number x' is equal to 3.1n - 5 + (12 / x) + 4.
