Solving Inequalities with Addition and Subtraction

What is the main focus of Chapter 6, Lesson 6?

• Solving inequalities by addition or subtraction

• Understanding geometric shapes

• Graphing linear equations

• Solving equations by multiplication or division

In the example problem, what is the maximum weight the pictures can be for Fisher to use the stamp?

• 9 ounces

• 10 ounces

• 13 ounces

• 11 ounces

What symbol is used to replace the equal sign in the inequality for the first-class stamp problem?

• Greater than

• Less than

• Less than or equal to

• Greater than or equal to

What happens to an inequality when you add or subtract the same number from both sides?

• The inequality becomes false

• The inequality remains true

• The inequality becomes an equation

• The inequality changes direction

If a is greater than b, what must be done to both sides of the inequality when adding c?

• Subtract c from both a and b

• Add c to both a and b

• Subtract c from b

• Add c to a only

What is an inequality?

• A solution to a quadratic equation

• A graph of a linear equation

• A mathematical sentence that shows equality

• A mathematical sentence that compares quantities

In the example x + 3 > 10, what is the solution for x?

• x > 7

• x = 10

• x < 7

• x = 7

How is the solution for a < 1.5 represented on a number line?

• An open dot at 1.5 with an arrow to the right

• A closed dot at 1.5 with an arrow to the left

• An open dot at 1.5 with an arrow to the left

• A closed dot at 1.5 with an arrow to the right

What does the term 'at most' indicate in an inequality?

• Greater than or equal to

• Less than

• Greater than

• Less than or equal to
