Whenever a number is followed by percent, you can turn it into a fraction by simply moving the decimal places two places to the left:
90.0 % becomes .90
As a fraction, this is 90 over 100. To reduce it to its simplest form, divide by 10:
9/10
The will be answer is 132
Hi,
![16 = - 5 + z4 \\ - 4z + 16 = - 5 \\ - 4z = - 5 - 16 \\ - 4z = -21](https://tex.z-dn.net/?f=16%20%3D%20-%205%20%2B%20z4%20%5C%5C%20-%204z%20%2B%2016%20%3D%20-%205%20%5C%5C%20-%204z%20%3D%20-%205%20-%2016%20%5C%5C%20-%204z%20%3D%20-21)
Now just divide both sides of equation by -4.
![z = \frac{21}{4}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B21%7D%7B4%7D%20)
Simplify:
![z = 5 \frac{1}{4} \: \: \: \: \: \: \: \: \: \: \: \: \: fraction \: result](https://tex.z-dn.net/?f=z%20%3D%205%20%5Cfrac%7B1%7D%7B4%7D%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20fraction%20%5C%3A%20result)
Decimal form:
![z = 5.25 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: decimal \: result](https://tex.z-dn.net/?f=z%20%3D%205.25%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20decimal%20%5C%3A%20result)
Hope this helps.

Answer:
Step-by-step explanation:
if u is an irrational number added to a rational number (sqrt 15) to yield 2, then that would mean u would = root -1.78.....
which means you wouldn't have a real solution. if you want a complex answer, it would be sqrt(1.78)i
