Answer 1

$\frac{5 + 0.8x}{ {x}^{2} + 5x } + \frac{1}{5x + 25} = \frac{5 + 0.8x}{x(x + 5)} + \frac{1}{5(x + 5)} = \frac{5(5 + 0.8x) + x}{5x(x + 5)} = \frac{25 + 4x + x}{5x(x + 5)} = \frac{25 + 5x}{5x(x + 5)} = \frac{5(5 + x)}{5x(x + 5)} = \frac{1}{x}$

$x = 0.01$

$\frac{1}{0.01} = 1 \div \frac{1}{100} = 1 \times 100 = 100$
