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, greater than or equal to, or less than or equal to the other.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. It indicates that the value on the left can be either less than or equal to the value on the right.

Front

How do you represent a situation where the total cost cannot exceed a certain amount using an inequality?

Back

You can represent it by setting up an inequality where the total cost expression is less than or equal to the maximum amount.

Front

What is the first step to solve the equation 3c + 8 = 20?

Back

The first step is to isolate the variable term by subtracting 8 from both sides, resulting in 3c = 12.

Front

What is the solution to the equation 435 - 2x = 401?

Back

The solution is x = 17.

Front

How do you set up an inequality for a situation where you need to collect more than a certain number of items?

Back

You set up an inequality where the total collected items plus the items to be collected is greater than the target number.

Front

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

Back

The symbol '>' means 'greater than'. It indicates that the value on the left is strictly greater than the value on the right.

Front

How do you solve the inequality 45 + 4x ≥ 125?

Back

First, subtract 45 from both sides to get 4x ≥ 80, then divide both sides by 4 to find x ≥ 20.

Front

What is the purpose of using variables in equations?

Back

Variables are used to represent unknown values in equations, allowing us to formulate and solve problems.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.
