Answer 3

It looks like you've provided a series of mathematical expressions. Let's solve each one step by step:

1. $12.5 - 4 - I_1 = 1.7 + \frac{0.4}{40} - 75 - 0.152$ Simplifying the left side: $8.5 - I_1 = 1.7 + 0.01 - 75 - 0.152$ Combining terms on the right side: $8.5 - I_1 = -72.482$ Solving for $I_1$: $I_1 = 8.5 + 72.482 = 80.982$

2. $40.75 - 0.152 = 0.15 + 0.25 \cdot 2$ Solving the left side: $40.598 = 0.15 + 0.5$ Simplifying the right side: $40.598 = 0.65$ The equation is not true, so there seems to be an error in the provided expressions or calculations.

If you meant something different or made a typo in the expressions, please provide the correct expressions or let me know how you'd like me to assist you further.
