Solving One-Step Adding/Subtracting Inequalities (5-1)

Front

What is an inequality?

Back

An inequality is a mathematical statement that shows the relationship between two expressions that are not equal, using symbols like <, >, ≤, or ≥.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. It indicates that one value is either less than or equal to another value.

Front

How do you solve the inequality -24 + k ≤ 10?

Back

To solve -24 + k ≤ 10, add 24 to both sides: k ≤ 34.

Front

What is the solution to the inequality 70 < x - 12?

Back

To solve 70 < x - 12, add 12 to both sides: x > 82. The correct value from the options is x = 100.

Front

Is 3 a solution to the inequality x > 10?

Back

No, because 3 is not greater than 10.

Front

How do you solve the inequality x + 5 > 7?

Back

To solve x + 5 > 7, subtract 5 from both sides: x > 2.

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. It indicates that one value is larger than another value.

Front

How do you interpret the inequality 23 < f + 12?

Back

To interpret 23 < f + 12, subtract 12 from both sides: f > 11.

Front

What is the solution to the inequality k ≤ 14?

Back

The solution means that k can be any value less than or equal to 14.

Front

What does it mean if x < 5?

Back

It means that x can be any value that is less than 5.
