evaluate $\frac{j}{k}-0.2k$ when $j = 25$ and $k = 5$.
evaluate $\frac{j}{k}-0.2k$ when $j = 25$ and $k = 5$.
Answer
Explanation:
Step1: Substitute values
Substitute $j = 25$ and $k = 5$ into $\frac{j}{k}-0.2k$. $\frac{25}{5}-0.2\times5$
Step2: Calculate division
Calculate $\frac{25}{5}$. $5 - 0.2\times5$
Step3: Calculate multiplication
Calculate $0.2\times5$. $5 - 1$
Step4: Calculate subtraction
$5-1 = 4$
Answer:
$4$
