Given:
[tex]1+4.25n+\frac{3}{2}p-3+\mleft(-2p\mright)+\frac{5}{4}n[/tex]Simplify the expression,
[tex]\begin{gathered} 1+4.25n+\frac{3}{2}p-3+\mleft(-2p\mright)+\frac{5}{4}n \\ (4.25+\frac{5}{4})n+(-2+\frac{3}{2})p-3+1 \\ 5.5n-\frac{1}{2}p-2 \end{gathered}[/tex]Answer:
[tex]5.5n-\frac{1}{2}p-2[/tex]
