Both men and women were aboard the mayflower. But look at the signature at the bottom what do you think is odd about this ? Why do you think this was?

Only men signed the mayflower compact.    

Explanation:                                                      

The Mayflower Compact signed aboard ship on November 11, 1620. There were total signatures of 41 men, starting with Governor John Carver and finishing with Edward Lester. Nine men on board did not sign the document. The Pilgrims (Separatists) reached to New World by Mayflower ship which carried about 102 passengers and formed Plymouth colony. At the bottom of the record, it's signed by people individually where they put their signatures in writing. It was a way of documenting the compact for the future where men onboard have agreed to follow rule and order upon landing on New World.    

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
