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 ≤ 7 means a is less than or equal to 7.

How do you solve the inequality: 20 - d < 14?

Back

Subtract 20 from both sides: -d < -6. Then multiply by -1 (reversing the inequality): d > 6.

Front

How do you solve the inequality: 12 - a > 8?

Back

Subtract 12 from both sides: -a > -4. Then multiply by -1 (reversing the inequality): a < 4.

Front

How do you solve the inequality: 15 + f > 25?

Back

Subtract 15 from both sides: f > 10.

Front

How do you solve the inequality: e + 4 ≤ -7?

Back

Subtract 4 from both sides: e ≤ -11.

Front

How do you solve the inequality: 7 + x ≤ 15?

Back

Subtract 7 from both sides: x ≤ 8.
