The Dred Scott decision had three important ramifications (results) on the slavery debate. Select all three. The Missouri Compromise was unconstitutional.
Slavery would be banned south of the 36º 30º parallel.
Slavery could not exist south of the Ohio River.
Slaves could never become citizens of the U. S.
Dred Scott is immediately freed from slavery.
Slaves cannot sue in federal court
The North must agree to the fugitive slave act and return any escaped slaves from the the South.

- "made the south's economy grow rapidly and a small effect that a lot of people don't know is that it made the more demand of slaves and cotton products. and also new states formed due to plantations growing in size."

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
