Answer 2

To simplify the expression 8.19 + a + (-5.8) + (-3.19) + 5.8, you can add or subtract the numbers:

8.19 + a - 5.8 - 3.19 + 5.8

Now, combine like terms:

(8.19 - 5.8 - 3.19) + a + 5.8

Now, perform the arithmetic operations within the parentheses:

(-0.8) + a + 5.8

Finally, simplify:

-0.8 + a + 5.8 = a + 5.8 - 0.8 = a + 5.0 = a + 5
