25 points What did the Soviet government explain was their reason for placing nuclear missiles in Cuba? What was the purpose of Kennedy's speech? What did he decide to do about the situation in Cuba? What does quarantine mean? (written answers, so there's no options)

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

i am pretty sure it is a

what are the reasons

i will need the answers to the problems. i took the test but cant remember the options. i would look up the questions that might .

for number 3, the answer is something about how they wanted to get sc to vote twords it, so they add the bill of rights or edited it.

for number 5, the answer is that it was even, they chose one side just as likely as they did the other.
