Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or equal to the other.

Front

How do you represent a situation where Maria has 15 dollars and a movie ticket costs 7 dollars?

Back

The inequality is f + 7 ≤ 15, where f is the amount Maria can spend on food and drinks.

Front

What does the inequality 14 ≤ -3x represent on a number line?

Back

It shows the values of x that satisfy the inequality, which can be represented by a specific section of the number line.

Front

What is the solution to the inequality -8x ≤ 38?

Back

The solution is x ≥ -4 3/4.

Front

What is the minimum length of each congruent side in an isosceles triangle if the perimeter is 78 inches or less?

Back

The minimum length must be greater than 16 inches, represented by the inequality x > 16.

Front

If the perimeter of an equilateral triangle is less than 20 feet, how do you express the side length?

Back

The inequality is 3x < 20, where x is the length of one side.

Front

What does the symbol '≤' mean in an inequality?

Back

It means 'less than or equal to'.

Front

What does the symbol '>' mean in an inequality?

Back

It means 'greater than'.

Front

How do you solve the inequality 3x + 5 < 20?

Back

Subtract 5 from both sides to get 3x < 15, then divide by 3 to find x < 5.

Front

What is the relationship between the sides of an isosceles triangle?

Back

In an isosceles triangle, at least two sides are of equal length.
