I don't really speak Spanish but I'll guess that says
How do I solve y = 1 - 2.5
Unless I'm missing something, there's not even any algebra here.
The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.
y = 1 - 2.5 = -(2.5 - 1) = -1.5
The anwer is 67/72 and can not be simpled any more
5530 mm is 553 cm and 5.53 m.
![5530 \: mm = \frac{5530}{10} = 553 \: cm \\ 553cm = \frac{553}{100 } = 5.53 \: m](https://tex.z-dn.net/?f=5530%20%5C%3A%20mm%20%3D%20%20%5Cfrac%7B5530%7D%7B10%7D%20%20%20%20%3D%20553%20%5C%3A%20cm%20%5C%5C%20553cm%20%3D%20%20%5Cfrac%7B553%7D%7B100%20%7D%20%20%20%20%3D%205.53%20%5C%3A%20m)
Let's see what to do...
_________________________________
Step (1)
Look : 16 , 10 , 4 , ...
It is an arithmetic sequence.
So first we have to find the value of the ratio(( d )) .
To do this, we need to subtract each sentence minus the previous sentence.
So we have : 10 - 16 = - 6
_________________________________
Step (2)
To find the nth sentence in an arithmetic sequence, we must use the following equation :
![t(n) = t(1) + (n - 1)d](https://tex.z-dn.net/?f=t%28n%29%20%3D%20t%281%29%20%2B%20%28n%20-%201%29d)
_________________________________
Step (3)
To find the 6th term just need to put the following parameters in the above sequence.
t(1) = 16 ------ n = 6 ------ d = -6
![t(6) = 16 + (6 - 1)( - 6)](https://tex.z-dn.net/?f=t%286%29%20%3D%2016%20%2B%20%286%20-%201%29%28%20-%206%29)
![t(6) = 16 + (5)( - 6)](https://tex.z-dn.net/?f=t%286%29%20%3D%2016%20%2B%20%285%29%28%20-%206%29)
![t(6) = 16 + ( - 30)](https://tex.z-dn.net/?f=t%286%29%20%3D%2016%20%2B%20%28%20-%2030%29)
![t(6) = 16 - 30](https://tex.z-dn.net/?f=t%286%29%20%3D%2016%20-%2030)
![t(6) = - 14](https://tex.z-dn.net/?f=t%286%29%20%3D%20%20-%2014)
