Answer:

15

Step-by-step explanation:

To figure this out you have to use the equation is over of equals percent over 100.

In this problem you are given the percent, 180, and the is, 27.

So you are trying to find the of so in the equation you will replace of with x.

27/x = 180/100

Now you have to do Cross Product Property

So 27*100 = 2700

180*x = 180x

180x = 2700

Now divide 180 by itself and 2700

180/180 = 1

2700/180 = 15

x = 15

So 180% of 15 is 27

How to solve it with walk through steps
mario62 [17]
You can say

x+y=5
x=5-y

You know the value of x, put it into the next equation.

3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y

Put y value back into either equation to find value of x.

x+y=5
x-2/5=5
x=5+2/5
x=27/5

Therefore, x,y = (27/5, -2/5)

Hope I helped :)
