Correct get Brainiest. Before the Europeans arrived in Africa, what people had already established a thriving slave trade there? A. British

B. Indians

C. Muslims

D. Portuguese

A. British

Explanation:

Before the end of the seventeenth century, England, France, Denmark, Holland, and Portugal had all established slave trading posts on the west African coast. Yet to simply say that Europeans purchased people who had already been enslaved seriously distorts historical reality.

The British is the correct answer.

the amount of the purse is, $120.

tax rate =9%

first find the the total tax she paid on the amount is equal to the 9% of $120 i.e,

now,

total amount paid by shalika = $120 +$10.8 = $130.8

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
