Consider the inequality [tex]x \leq 82[/tex]. Which values of [tex]x[/tex] are possible solutions to the inequality?

A. [tex]82, 81.5, 0[/tex], and [tex]-4[/tex]
B. [tex]82, 85, 95.5[/tex], and [tex]100[/tex]
C. [tex]82.5, 12, 10.5[/tex], and [tex]0[/tex]
D. [tex]82.5, 87, 90[/tex], and [tex]100[/tex]

Answer :

To solve the inequality [tex]\(x \leq 82\)[/tex], we need to determine which values of [tex]\(x\)[/tex] satisfy this condition. We're given a set of possible answers, and we have to check each set to see if all its values satisfy the inequality.

Let's go through each option step-by-step:

Option A: 82, 81.5, 0, and -4
- Check if 82 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 82 is equal to 82.
- Check if 81.5 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 81.5 is less than 82.
- Check if 0 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 0 is less than 82.
- Check if -4 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because -4 is less than 82.

All numbers in Option A satisfy the inequality.

Option B: 82, 85, 95.5, and 100
- Check if 82 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 82 is equal to 82.
- Check if 85 satisfies [tex]\(x \leq 82\)[/tex]: No, because 85 is greater than 82.
- Check if 95.5 satisfies [tex]\(x \leq 82\)[/tex]: No, because 95.5 is greater than 82.
- Check if 100 satisfies [tex]\(x \leq 82\)[/tex]: No, because 100 is greater than 82.

Not all numbers in Option B satisfy the inequality.

Option C: 82.5, 12, 10.5, and 0
- Check if 82.5 satisfies [tex]\(x \leq 82\)[/tex]: No, because 82.5 is greater than 82.
- Check if 12 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 12 is less than 82.
- Check if 10.5 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 10.5 is less than 82.
- Check if 0 satisfies [tex]\(x \leq 82\)[/tex]: Yes, because 0 is less than 82.

Not all numbers in Option C satisfy the inequality.

Option D: 82.5, 87, 90, and 100
- Check if 82.5 satisfies [tex]\(x \leq 82\)[/tex]: No, because 82.5 is greater than 82.
- Check if 87 satisfies [tex]\(x \leq 82\)[/tex]: No, because 87 is greater than 82.
- Check if 90 satisfies [tex]\(x \leq 82\)[/tex]: No, because 90 is greater than 82.
- Check if 100 satisfies [tex]\(x \leq 82\)[/tex]: No, because 100 is greater than 82.

All numbers in Option D are greater than 82 and do not satisfy the inequality.

Therefore, after evaluating each option, we find that Option A (82, 81.5, 0, and -4) contains values that all satisfy the inequality [tex]\(x \leq 82\)[/tex]. So, the correct answer is Option A.
