Given:
There are given the expression:
[tex]\begin{gathered} -2.65-16.3\text{ and} \\ 23.5+(-62.74) \end{gathered}[/tex]Explanation:
To find the value of the expression, we need to subtract 16.3 from the -2.65.
Then,
[tex]-2.65-16.3=-18.95[/tex]And,
In the next expression, we need to add 23.5 with (-62.74).
So,
[tex]\begin{gathered} 23.5+(-62.74)=23.5-62.74 \\ =-39.24 \end{gathered}[/tex]Final answer:
Hence, the value of the expressions is shown below:
