Equations & Inequalities Remediation

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'. It indicates that a value can be either greater than or equal to a specified number.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'. It indicates that a value can be either less than or equal to a specified number.

Front

How do you solve the equation r - 11 = 5?

Back

To solve for r, add 11 to both sides: r = 5 + 11, so r = 16.

Front

What is the solution to the equation 9 = n + 3?

Back

To solve for n, subtract 3 from both sides: n = 9 - 3, so n = 6.

Front

What is the first step in solving the equation x + 9 = 24?

Back

Subtract 9 from both sides to isolate x: x = 24 - 9.

Front

What is the solution to the equation a > 11?

Back

The solution includes all values of a that are greater than 11.

Front

What is the solution to the inequality a < 11?

Back

The solution includes all values of a that are less than 11.

Front

How do you represent the solution of an inequality on a number line?

Back

Use an open circle for < or > and a closed circle for ≤ or ≥, then shade the appropriate direction.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater or less than another.
