Answer 3

To find the values of the expression 2•a/5 for different values of a, you can follow these steps:

1. Substitute the given values of a (250, 350, and 450) into the expression 2•a/5.
2. Perform the calculations.

Let's do it step by step:

1. For a = 250: 2•a/5 = 2•250/5 = 500/5 = 100

2. For a = 350: 2•a/5 = 2•350/5 = 700/5 = 140

3. For a = 450: 2•a/5 = 2•450/5 = 900/5 = 180

So, the values of the expression 2•a/5 for a = 250, 350, and 450 are 100, 140, and 180, respectively.
