I think you’re asking why 10 is there when you when from _/100? if so it’s because 10 is the square root of 100. 10 x 10 = 100. similar to how the square root of 4 is 2 and 25 would be 5. or 16 is 4.

A recipe for salsa uses 65% tomatoes. If a batch contains 5.2 cups of tomatoes, how large is the batch of salsa.

Artemon [7]

so the salsa uses 65% of tomatoes, and it just so happen for that is 5.2 cups.

let's say the salsa is "x" cups, namely 100%, and we know that 5.2 cups is 65%, thus

$\bf \begin{array}{ccll} cups&\%\\ \cline{1-2} 5.2&65\\ x&100 \end{array}\implies \cfrac{5.2}{x}=\cfrac{65}{100}\implies \cfrac{5.2}{x}=\cfrac{13}{20}\implies 104=13x \\\\\\ \cfrac{104}{13}=x\implies 8=x$

Olegator [25]

Answer:

84 minutes (1 hr and 24 mins)

Step-by-step explanation:

If the bill is $26, then that is what the equation will be equal to.
$5 fee will be added
$0.25 is 'per minute' so this is the number with the $x$

Let's put it together:

26 = 5 + .25 $x$

Subtract the 5...

21 = .25 $x$

Divide...

$\frac{21}{.25} = 84$
