What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is greater than 5.

Front

What does the symbol '<' mean in inequalities?

Back

The symbol '<' means 'less than'. For example, y < 3 means y is less than 3.

Front

What does the symbol '≥' mean in inequalities?

Back

The symbol '≥' means 'greater than or equal to'. For example, z ≥ 4 means z is greater than or equal to 4.

Front

What does the symbol '≤' mean in inequalities?

Back

The symbol '≤' means 'less than or equal to'. For example, a ≤ 10 means a is less than or equal to 10.

Front

How do you solve the inequality x + 3 < 7?

Back

Subtract 3 from both sides: x < 4.

Front

How do you solve the inequality 2y ≥ 10?

Back

Divide both sides by 2: y ≥ 5.

Front

What is the solution to the inequality -4 + y < -8?

Back

Add 4 to both sides: y < -4.

Front

How do you check if a value satisfies the inequality x + 9 > 21 when x = 15?

Back

Substitute 15 into the inequality: 15 + 9 > 21 is true.

Front

What is the solution to the inequality 26 < p + 28?

Back

Subtract 28 from both sides: p > -2.
