To add the expressions \( (2.5x + 3) + (5x - 1.2) \), we can combine like terms.
1. Combine the coefficients of \( x \):
\[
2.5x + 5x = 7.5x
\]
2. Combine the constant terms:
\[
3 - 1.2 = 1.8
\]
Now, putting it all together, we have:
\[
(2.5x + 3) + (5x - 1.2) = 7.5x + 1.8
\]
Thus, the final result is:
\[
7.5x + 1.8
\]
