Evaluate each expression for the given value 2/ 5 - 3 1 /2 for k = 15

Answer: The value of expression for k = 15 is  [tex]\frac{13}{5}[/tex]   Step-by-step explanation:Given expression as :[tex]\frac{2}{5}[/tex] k - 3 [tex]\frac{2}{5}[/tex]  Or, [tex]\frac{2}{5}[/tex] k - 3  - [tex]\frac{2}{5}[/tex]  Or, [tex]\frac{2}{5}[/tex] k - [tex]\frac{17}{5}[/tex]  Now, for k = 15The expression is [tex]\frac{2}{5}[/tex] × 15 - [tex]\frac{17}{5}[/tex]  Or, [tex]\frac{30}{5}[/tex]  - [tex]\frac{17}{5}[/tex]  Or, 6 - [tex]\frac{17}{5}[/tex]  Or, [tex]\frac{30-17}{5}[/tex]  So, [tex]\frac{13}{5}[/tex]  Hence The value of expression for k = 15 is  [tex]\frac{13}{5}[/tex]   Answer
