04.03 Sparta and Athens What Do I Have To Do? In this lesson, you learned about the city-states of Athens and Sparta. Suppose that you are an Athenian visiting Sparta, or a Spartan who has received permission to visit Athens. You must write a letter to a friend at home telling him or her about your visit. Although Athens and Sparta were both Greek and shared some common elements of Greek culture, they were also very different.

i would think it's industries and hydroelectric power

warfare was the primary means of cultural transmission in both regions.

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
