Answer:
16.875 spiders
Step-by-step explanation:
Given
Let
![B = Beetles](https://tex.z-dn.net/?f=B%20%3D%20Beetles)
![C = Birds](https://tex.z-dn.net/?f=C%20%3D%20Birds)
![S = Spiders](https://tex.z-dn.net/?f=S%20%3D%20Spiders)
So, we have:
--- equal amounts
--- 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](https://tex.z-dn.net/?f=6B%20%2B%202C%20%2B%208S%20%3D%20270)
![6S + 2S + 8S = 270](https://tex.z-dn.net/?f=6S%20%2B%202S%20%2B%208S%20%3D%20270)
![16S = 270](https://tex.z-dn.net/?f=16S%20%3D%20270)
Solve for S
![S = \frac{270}{16}](https://tex.z-dn.net/?f=S%20%3D%20%5Cfrac%7B270%7D%7B16%7D)
![S = 16.875](https://tex.z-dn.net/?f=S%20%3D%2016.875)
<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>
3/5 block mile is also 0.6 block mile
4 1/2 miles is also 4.5 miles
How many 0.6mi blocks do you run to run 4.5 miles?
4.5miles/0.6block mi = 7.5 or 7 1/2 blocks will equal 4.5 or 4 1/2 miles.
Check 7.5 blocks x 0.6 block mi = 4.5 miles
