Question

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

Answer 1

Answer:

The value of expression for k = 15 is  $\frac{13}{5}$  

Step-by-step explanation:

Given expression as :

$\frac{2}{5}$ k - 3 $\frac{2}{5}$  

Or, $\frac{2}{5}$ k - 3  - $\frac{2}{5}$  

Or, $\frac{2}{5}$ k - $\frac{17}{5}$  

Now, for k = 15

The expression is

$\frac{2}{5}$ × 15 - $\frac{17}{5}$  

Or, $\frac{30}{5}$  - $\frac{17}{5}$  

Or, 6 - $\frac{17}{5}$  

Or, $\frac{30-17}{5}$  

So, $\frac{13}{5}$  

Hence The value of expression for k = 15 is  $\frac{13}{5}$   Answer
