### Eureka Math Grade 6 Module 4 Lesson 25 Opening Exercise Answer Key

Opening Exercise:

Identify a value for the variable that would make each equation or inequality into a true number sentence. Is this the only possible answer? State when the equation or inequality is true using equality and inequality symbols.

a. 3 + g = 15
12 is the only value of g that will make the equation true. The equation is true when g = 12.

b. 30 > 2d
Answers will vary. There is more than one value of d that will make the inequality true. The inequality is true when d < 15.

c. $$\frac{15}{f}$$ < 5
Answers will vary. There is more than one value off that will make the inequality true. The inequality is true when f > 3.

d. 42 ≤ 50 – m
Answers will vary. There is more than one value of m that will make the inequality true. The inequality is true when m ≤ 8.
