What is an inequality?

Back

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

How do you write an inequality for a situation?

Back

To write an inequality, identify the variable, the maximum or minimum value, and the relationship (less than, greater than, etc.). For example, if Mia wants to spend less than $500, the inequality would be: 150 + 35h < 500.

What does the slope of a line represent in a graph?

Back

The slope of a line represents the rate of change between the two variables. It shows how much one variable changes for a unit change in another variable.

How do you find the total distance covered by multiple team members?

Back

To find the total distance, add the distances covered by each team member. For example, if one runs 5/6 mile, another swims 1/12 mile, and the last bicycles 7/8 mile, the total is 5/6 + 1/12 + 7/8.

Front

What is the first step in solving an inequality?

Back

The first step in solving an inequality is to isolate the variable on one side of the inequality sign.

Front

How do you graph an inequality on a number line?

Back

To graph an inequality on a number line, draw an open circle for < or > and a closed circle for ≤ or ≥ at the value, then shade the direction indicated by the inequality.

What is the formula to calculate a percentage?

Back

The formula to calculate a percentage is: (part/whole) × 100. For example, if 30 out of 75 people got tickets, the percentage is (30/75) × 100 = 40%.

Front

What does it mean to solve an inequality?

Back

To solve an inequality means to find all values of the variable that make the inequality true.

Front

How do you convert mixed numbers to improper fractions?

Back

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that result over the original denominator.

What is the relationship between the cost and time in a rental situation?

Back

The relationship between cost and time in a rental situation is often linear, where the cost increases at a constant rate per unit of time.
