africa, the second-largest continent, is bounded by the mediterranean sea, the red sea, the indian ocean, and the atlantic ocean. it is divided in half almost equally by the equator. the continent includes the islands of cape verde, madagascar, mauritius, seychelles, and comoros.

africa’s physical geography, environment and resources, and human geography can be considered separately.

the origin of the name “africa” is greatly disputed by scholars. most believe it stems from words used by the phoenicians, greeks, and romans. important words include the egyptian word afru-ika, meaning “motherland”; the greek word aphrike, meaning “without cold”; and the latin word aprica, meaning “sunny.”

today, africa is home to more countries than any other continent in the world. these countries are: morocco, western sahara (morocco), algeria, tunisia, libya, egypt, sudan, chad, niger, mali, mauritania, senegal, the gambia, guinea-bissau, guinea, sierra leone, liberia, côte d’ivoire, ghana, burkina faso, togo, benin, nigeria, cameroon, central africa republic, equatorial guinea, gabon, congo, democratic republic of the congo, angola, namibia, botswana, south africa, lesotho, swaziland, mozambique, zimbabwe, zambia, malawi, tanzania, rwanda, burundi, uganda, kenya, somalia, ethiopia, djibouti, eritrea and the island countries of cape verde, madagascar, mauritius, seychelles, and comoros.

ba geologist finds four sedimentary rock she determines that no geologic events have shifted the layers she labeles them a,b,c,dbfrom top to bottom

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
