Solve the given inequality 7 - 2 x ≥ x - 5

Given that, 7 - 2 x ≥ x - 5 Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions, In the given inequality, 7 - 2 x ≥ x - 5 - 2 x - x ≥ - 5 - 7 - 3 x ≥ - 12 Hence, x ≥ 4

Solve the given inequality x 2 + 2 x ≥ 5

Given that, x 2 + 2 x ≥ 5 Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions, In the given inequality, x + 4 x ≥ 10 5 x ≥ 10 x ≥ 2 Hence, x ≥ 2

Solve the given inequality 25 + 2 x 3 > 35 - x

Given that, 25 + 2 x 3 > 35 - x 2 x 3 + x > 35 - 25 (Multiply by 3 on both sides) Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions, In the given inequality, 2 x + 3 x > 3 × 10 5 x > 30 x > 6 Hence, x > 6

Solve the given inequality 3 x 4 + 5 ≤ 1 2 - 6 x

Given that, 3 x 4 + 5 ≤ 1 2 - 6 x 3 x 4 + 6 x ≤ 1 2 - 5 (multiply by 4 on both sides) Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions, In the given inequality, 3 x + 24 x ≥ 2 - 20 27 x ≤ - 18 x ≤ - 18 27 Hence, x ≤ - 2 3
