How can you use mental math to determine if a ratio is simplified

Mathematics

You can see if it is simplified by checking if the numbers can be divided with the same number. Typically, this is done mentally.
Ex: You can mentally determine that 10:4 is not simplified, because both can be divided by 2.
You can then determine that 5:2 is simplified.

Solve algebraically for x: 4-√2x-5) = 1
klemol [59]
Here's how to solve this equation:

4 - <span>√2x-5 = 1
</span><span>√2x-5 = 4-1
</span><span>√2x-5 = 3 (now we have to square both sides to get rid of the root)
</span><span>√2x-5=3  / ^2
</span>(<span>√2x-5)^2 = 3^2
2x-5 = 9
2x = 9+5
2x = 14
x = 14/2
x = 7

The correct answer is 7. </span>
