25 x 4= 100 so you would do this 3 times because you would do
25 x 4 + 25 x 4 + 25 x 4= 300
Lets say there are 5 sea urchins. The number of sea horses is times 4. So 5 times 4 is 25.
So there are 25 sea urchins!
Answer:
![22 < X < 46](https://tex.z-dn.net/?f=22%20%3C%20X%20%3C%2046)
Step-by-step explanation:
Given
Two sides of a triangle; 34 and 12
Required
Determine the range of the third side
Represent the third side with X
To determine the range of the third side; two of the following conditions must be satisfied'
![34 + X > 12](https://tex.z-dn.net/?f=34%20%2B%20X%20%3E%2012)
![34 + 12 > X](https://tex.z-dn.net/?f=34%20%2B%2012%20%3E%20X)
![12 + X > 34](https://tex.z-dn.net/?f=12%20%2B%20X%20%3E%2034)
Solving 34 + X > 12
<em>Subtract 34 from both sides</em>
![34 - 34 + X> 12 - 34](https://tex.z-dn.net/?f=34%20-%2034%20%2B%20X%3E%2012%20-%2034)
![X > -22](https://tex.z-dn.net/?f=X%20%3E%20-22)
Solving 34 + 12 > X
![34 + 12 > X](https://tex.z-dn.net/?f=34%20%2B%2012%20%3E%20X)
![46 > X](https://tex.z-dn.net/?f=46%20%3E%20X)
Solving 12+ X > 34
<em>Subtract 12 from both sides</em>
![12 - 12 + X > 34 -12](https://tex.z-dn.net/?f=12%20-%2012%20%2B%20X%20%3E%2034%20-12)
![X > 22](https://tex.z-dn.net/?f=X%20%3E%2022)
Write out the results
![X > -22](https://tex.z-dn.net/?f=X%20%3E%20-22)
![46 > X](https://tex.z-dn.net/?f=46%20%3E%20X)
![X > 22](https://tex.z-dn.net/?f=X%20%3E%2022)
The first inequality will be discarded because it accommodates negative digits;
<em>So, we're left with</em>
and ![X > 22](https://tex.z-dn.net/?f=X%20%3E%2022)
This can be rewritten as
and ![22 < X](https://tex.z-dn.net/?f=22%20%3C%20X)
Combine both inequalities;
![22 < X < 46](https://tex.z-dn.net/?f=22%20%3C%20X%20%3C%2046)
Hence, the range of the third length is ![22 < X < 46](https://tex.z-dn.net/?f=22%20%3C%20X%20%3C%2046)
1 1/2 or 3/2 because there is 4 more than 8 which is a half.
