Week 15~Tuesday

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 not equal to the other.

Front

How do you graph an inequality on a number line?

Back

To graph an inequality, use an open circle for < or > and a closed circle for ≤ or ≥. Shade the region that represents the solutions.

Front

What does it mean for a number to be a solution to an inequality?

Back

A number is a solution to an inequality if it makes the inequality true when substituted into the expression.

Front

What is the formula to calculate earnings based on hourly wage and hours worked?

Back

Earnings = Hourly Wage × Hours Worked.

Front

If Cindy works 15 hours and Zoey works 20 hours at $6.25 per hour, how do you express their total earnings?

Back

Total Earnings = 6.25(15 + 20).

Front

What is the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of all three sides.

Front

How do you set up an equation to find the value of a variable in a triangle's perimeter?

Back

Set the sum of the expressions for the sides equal to the given perimeter.

Front

What is the solution to the inequality -22 < m - 57?

Back

To solve, add 57 to both sides: m > 35.

Front

What does it mean for a number to be a possible solution to an inequality?

Back

A possible solution is a number that, when substituted into the inequality, satisfies the condition.

Front

What is the significance of the perimeter in geometry?

Back

The perimeter is important for understanding the size and dimensions of geometric shapes.
