Solving one step inequalities

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 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'.

Front

How do you solve the inequality y - 13 ≤ -15?

Back

Add 13 to both sides: y ≤ -2.

Front

What is the solution to the inequality 24 ≤ h + 15?

Back

Subtract 15 from both sides: h ≥ 9.

Front

If x + 9 > 21, what is the value of x?

Back

Subtract 9 from both sides: x > 12.

Front

What does it mean for a value to satisfy an inequality?

Back

A value satisfies an inequality if, when substituted into the inequality, the statement is true.

Front

Match the inequality 11 < a with its graph.

Back

The graph shows a line starting from 11 and extending to the right, not including 11.

Front

What is the first step in solving the inequality 3x + 5 < 14?

Back

Subtract 5 from both sides: 3x < 9.

Front

What is the solution to the inequality -2x ≥ 6?

Back

Divide both sides by -2 (remember to flip the inequality): x ≤ -3.
