When we are given information on different products and are asked to calculate a result from these, we are generally being provided with equations, in this case to calculate the number of bags required to make the requested mixture we have the following equations:

$29A+18B=181\\3A+25B=65\\4A+6B=32$

Where A and B represent the number of bosas of each fertilizer brand, as we have two unknowns we will use two equations like this:

$1) 3A+25B=65\\2) 4A+6B=32$

One incognita is cleared depending on the other

$2) 4A+6B=32\\4A=32-6B\\A=8-\frac{6}{4} B$

The values obtained in the second are replaced

$1) 3A+25B=65\\3(8-\frac{6}{4} B)+25B=65\\24-\frac{18}{4} B+25B=65\\B(-\frac{18}{4}+\frac{100}{4})=41\\B(\frac{82}{4})=41\\B(\frac{41}{2})=41\\B=2$

With the value of B it is replaced in the first one to obtain the value of A:

$A=8-\frac{6}{4} B\\A=8-\frac{12}{4}\\A=8-3\\A=5$

Answer:

The answer is 6

Step-by-step explanation:

$\lim_{x \to 4} \frac{x^3 - 64}{x^2 - 16} \\\\= \lim_{x \to 4} \frac{x^3 - 64}{(x + 4)(x - 4)} \\\\=\lim_{x \to 4} \frac{(x^2 + 4x + 16)(x - 4)}{(x + 4)(x - 4)} \\\\= \lim_{x \to 4} \frac{(x^2 + 4x + 16)}{(x + 4)} \\\\= (16 + 16 + 16) / 8\\= 48 / 8\\= 6$
