Nine increased by the product of a number and 7 is less than -16.
To translate the given sentence into an inequality, you need to identify the key elements and their corresponding mathematical operations.
First, let's identify the key elements:
- "A number x" represents an unknown number.
- "Increased by 7" indicates that 7 is added to the unknown number.
- "Is less than or equal to 20" means that the result of the addition should be less than or equal to 20.
To express this in mathematical notation, you can use the variable x to represent the unknown number.
The statement "A number x increased by 7 is less than or equal to 20" can be written as the inequality:
x + 7 ≤ 20
So the inequality representing the given sentence is x + 7 ≤ 20.
