Answer 2

It looks like you've provided three mathematical expressions. Let's go through each of them step by step:

1. $\frac{25x - 36}{\frac{1}{5}x + 6}$:

To simplify this expression, we'll first simplify the denominator by multiplying it by 5 to get rid of the fraction:

$\frac{25x - 36}{\frac{1}{5}x + 6} \cdot \frac{5}{5} = \frac{5(25x - 36)}{x + 30}$

Now we can cancel out the common factors:

$= \frac{5(5x - 9)}{x + 30}$

This is the simplified expression.

2. $\frac{48x - 6}{6x + 5y} \cdot (0, 1 + 0,5)$:

It seems like you're trying to plug in values for $x$ and $y$. Let's do that:

$\frac{48x - 6}{6x + 5y} \cdot (0, 1 + 0,5) = \frac{48(0) - 6}{6(0) + 5(1 + 0.5)}$

$= \frac{0 - 6}{0 + 5(1.5)} = \frac{-6}{7.5}$

$= -\frac{4}{5}$

3. $(17x - 11) \cdot (2 - 3z) \cdot (0.5 + 0.1)$:

Let's simplify each part of this expression step by step:

$= (17x - 11) \cdot (2 - 3z) \cdot (0.6)$

$= (34x - 22) \cdot (0.6 - 0.6z)$

This is the simplified expression.

Please double-check the original expressions and calculations to ensure accuracy. If you have any further questions, feel free to ask!
