Answer:
The value of the expression is 19
Step-by-step explanation:
We want to find the value of the expression: [tex]-8+19+8[/tex]
We regroup the numbers to make the computation very easy for us.
[tex]-8+8+19[/tex]
Recall that -x+x are zero pairs.
This implies that:
[tex]-8+8+19=0+19[/tex]
Also zero is the identity element of addition of of real numbers
[tex]0+19=19[/tex]
Hence the correct answer is 19
