X = 16/7 Because if you substitute -5 in for y you get x = 16/7 and you can check by plugging in 16/7 in for x and you get -5 for y so your answer is: x=16/7

What percent of 50 is 18

Rom4ik [11]

Answer:
36%

Explanation:
To get the percentage of a fraction, we follow these steps:
1- simplify the fraction (get its simplest form)
2- multiply this simplest form by 100%

For the given, we have:
1- the fraction is $\frac{18}{50}$
We can note that both the numerator and denominator are divisible by 2. Therefore, we can reduce the fraction into $\frac{9}{25}$

2- Since no further simplification can be applied, therefore, our simplest form is $\frac{9}{25}$

3- we multiply this simplest form by 100%:
$\frac{9}{25}$ * 100 = 36%

Based on the above:
18 is 36% of 50

Hope this helps :)
