GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

$\frac{x^{2}+6}{x-6}$

Troyanec [42]

Answer:

Percentage of Taxes = 10.689 %

Step-by-step explanation:

Total earning of Anna is $442.50

The amount which is held with Taxes = $47.30

Now in terms of percentage

percentage of taxes from her total earning = $\frac{47.30}{442.50} times 100$

So % taxes = ( 0.106892) × 100

∴ Taxes percentage = 10.689 %
