Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

$B = Beetles$

$C = Birds$

$S = Spiders$

So, we have:

$B = C = S$ --- equal amounts

$6B + 2C + 8S = 270$ --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

$6B + 2C + 8S = 270$

$6S + 2S + 8S = 270$

$16S = 270$

Solve for S

$S = \frac{270}{16}$

$S = 16.875$

<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>
