Given is 1/2(10x+20y+10z)

Simplifying the given expression using Algebra properties.

$\frac{1}{2} (10x+20y+10z) \\\\Step \;1: \;Using \;Distribution \;property \\\\=\frac{10x}{2}+ \frac{20y}{2}+ \frac{10z}{2} \\\\Step \;2: \;Dividing \\\\=5x+10y+5z \\\\Step \;3: \;Factoring \;out \;common \;factor \\\\= 5*(x+2y+z)$

Hence, the final answer would be (5x + 10y + 5z) or 5·(x + 2y + z).
