Question

Which inequality represents the following sentence?

Twelve fewer than a number is at least 18.

12 + x ≤ 18
x – 12 ≥ 18 (This one correct?)
12 – x ≥ 18
x – 12 < 18,

Answer 1

x – 12 ≥ 18 Let's break down the sentence and create an inequality from it. We'll use X to represent the number. "Twelve fewer than a number is at least 18." The "Twelve fewer than a number" indicates subtraction, so let's do that. X - 12 "is at least 18." would be a greater than or equal relationship. So we have X - 12 ≥ 18 And we're done. The desired equation is: x – 12 ≥ 18

Answer 2

B) x - 12 ≥ 18.

Explanation:

Given : Twelve fewer than a number is at least 18.

To find : Which inequality represents the following sentence?.

Solution : We have given

Twelve fewer than a number is at least 18.

Let the number be x .

According to question :

Twelve is less than a number x .

x - 12 ( negative sign used for fewer).

x - 12 ≥ 18.

Here we used greater than equal to sign because x- 12 is at least 18 mean is must be 18 or greater than 18.

Then equation become x - 12 ≥ 18.

Therefore, B) x - 12 ≥ 18.
