evaluate (0.3y+\frac{y}{z}) when (y = 10) and (z = 5).

Explanation:

Step1: Substitute the values

Substitute $y = 10$ and $z = 5$ into the expression $0.3y+\frac{y}{z}$. We get $0.3\times10+\frac{10}{5}$.

Step2: Calculate each part

First, calculate $0.3\times10 = 3$. Second, calculate $\frac{10}{5}=2$.

Step3: Add the results

Add the two results together: $3 + 2$. $3+2=5$

Answer:

$5$
