The sum of 4.5 and one-third a number is equal to at most 38.9. What are all the possible values of the number? How would you write an inequality that could be used to solve this problem

1 answer

Let's assume the number as "x".

According to the given information, the sum of 4.5 and one-third of the number is at most 38.9. Mathematically, we can write this as:

4.5 + (1/3)x ≤ 38.9

To solve this inequality, we can subtract 4.5 from both sides:

(1/3)x ≤ 38.9 - 4.5

Simplifying the right side:

(1/3)x ≤ 34.4

To isolate x, we can multiply both sides by 3:

3 * (1/3)x ≤ 3 * 34.4

This simplifies to:

x ≤ 103.2

Therefore, all possible values of the number (x) are less than or equal to 103.2. To represent this in an inequality, we can write:

x ≤ 103.2
