Answer 2

To solve the expression 5.51 + (-6.8) + (-8.51) + 6.8, we need to substitute the value of "a" with -4 7/13.

First, let's simplify the addition and subtraction operations:

5.51 + (-6.8) + (-8.51) + 6.8

= 5.51 - 6.8 - 8.51 + 6.8 (since adding a negative number is the same as subtracting a positive number)

Next, let's perform the subtraction:

= (5.51 - 8.51) - (6.8 - 6.8)

= -3 - 0

= -3

Therefore, the value of the expression 5.51 + (-6.8) + (-8.51) + 6.8, when a is equal to -4 7/13, is -3.
