MGSE6.EE.5:

I can understand the process of solving an inequality as answering a question and use substitution IOT assess the reasonableness of a solution to an inequality.

Multiple Choice

Which answer represents an equation?

• 1 + 1 = 2

• 1 + 1

• 1 > 0

Multiple Choice

Which answer represents an inequality?

• 2 + 2 = 4

• 2 < 3

• 2 + 2

Multiple Choice

Which answer represents an expression?

• 3 + 3 = 6

• 3 + 3

• 3 > 4

Solve the inequality to see if it is true or false.

• 2 ⋅ 3 ≥ 4

• Perform operations on both sides of inequality (in this case, multiplication - 2 times 3)

• 6 ≥ 4

• Is 6 greater than or equal to 4?

• Yes! So the inequality is true.

Multiple Choice

Solve the inequality to see if it is true or false.

10 + 10 > 15

• True

• False

Multiple Choice

12 - 4 > 10

• True

• False

Multiple Choice

3 ⋅ 3 < 10

• True

• False

Multiple Choice

10 ÷ 5 ≥ 9

• True

• False

Use substitution to solve the inequality.

• a ≥ 4, when a=5

• Substitute the value (number) for the variable (letter)

• 5 ≥ 4

• Is 5 greater than or equal to 4?

• Yes! So the inequality is true.

Multiple Choice

b < 9, when b=8

• True

• False

Use substitution to solve the inequality.

• a + 1 > 4, when a=5

• Substitute the value (number) for the variable (letter)

• 5 + 1 > 4 - Simplify... 6 > 4

• Is 6 greater than 4?

• Yes! So the inequality is true.

Multiple Choice

y - 5 > 11, when y=15

• True

• False

Multiple Choice

t + 10 > 19, when t=13

• True

• False
