What nation was the first to make a coronavirus vaccine available to its citizens, even though it's still in a trial phase? (This does not include
unrecognized vaccines in China and Russia)

two months after his defeat of napoleon bonaparte's colonial forces, jean-jacques dessalines proclaims the independence of saint-domingue, renaming it haiti after its original arawak name. in 1791, a slave revolt erupted on the french colony, and toussaint-louverture, a former slave, took control of the rebels.

the dominoes began to fall. the surrender at appomattox took place a week later on april 9. while it was the most significant surrender to take place during the civil war, gen. robert e. lee, the confederacy's most respected commander, surrendered only his army of northern virginia to union gen. ulysses s. grant

explanation:

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
