Solving One-Variable Inequalities

Question 1 • AZ-Algebra 1A (MA101)

Which interval is the solution set to 0.35x – 4.8 < 5.2 – 0.9x?(–∞, –8)(–∞, 8)(–8, ∞)(8, ∞)

Answer
A
(–∞, –8)
B
(–∞, 8)
C
(–8, ∞)
D
(8, ∞)

Explanation

Add 0.9x to both sides and add 4.8 to both sides: 1.25x < 10. Dividing by the positive number 1.25 keeps the inequality direction the same, giving x < 8. The solution is (–∞, 8), choice B.
