Does anybody knows the philosophy of ferdinand de magellan? ?

Magalhaes was a  16th-century Portuguese sailor, one of the crucial people who helped to discover the true nature of the world. I suppose he was a sort of revolutionnary who questioned an old dogma about plane Earth and believed that the Earth is round.

Explanation: Magalhaes reached West Indies, discovered Philipines, travelled all around the world. He was not a theorist like Copernicus, but experienced that the Earth is round.

b. sec, foreign relations

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
