Answer:

y is equal to -1

x is equal to 4

Step-by-step explanation:

The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.

Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.

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 :)
