Add the same number 5 to both sides of -4 ≤ -2. The result is:
A1 ≤ 3 — Rule 1 (adding equal numbers does NOT change the sign of inequality)
B-9 ≤ -7
C-1 ≥ -3
D5 ≤ 7
Answer & Solution
Correct answer: A. 1 ≤ 3 — Rule 1 (adding equal numbers does NOT change the sign of inequality)
Rule 1: equal numbers may be added (or subtracted) on both sides without changing the inequality sign. -4 + 5 = 1; -2 + 5 = 3 → 1 ≤ 3.
