MRY Ch 1.5 Complete Lesson: Solving Inequalities Using Addition or Subtraction

1

Solve It! What is the least number of states in the southeastern U.S. that the candidate could win and still become president? (Hint: the number inside the state on the map represents the number of electoral votes for that state. Only 32 electoral votes would be needed)
Enter only a number.

4

Use Your Vocabulary: Categorize each of the equations.

3 = x
x = 1/3
x + 2 = 5
x + 2 = 5 - 2

Equivalent to the equation x = 3
Not equivalent to the equation x = 3

4

Use Your Vocabulary: Categorize each of the inequalities.

3 ≥ x
x ≤ 1/3
x + 2 ≥ 5
x + 2 ≤ 5 - 2

Equivalent to x ≤ 3
Not equivalent to x ≤ 3
