It would be n + ( 8 + 6 ) because n is separated from the addition of 8 and 6 as asked in the question.
The percent increase from April to May is 30%.
In order to find this we must use the percent change formula. It is listed below.
(New - Old)/Old *100 = Percent Change
Now we can plug in known values to determine the percent change.
(390 - 300)/300 * 100 = Percent Change
90/300 * 100 = Percent Change
.30 * 100 = Percent Change
30% = Percent Change
<u>Answer:</u>
$142500
<u>Step-by-step explanation:</u>
We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.
If the sum of the two salaries is $190000, we are to find the salary of the president of the University.
Let
to be the department head's salary, we can write an equation:
![3x+x=190000](https://tex.z-dn.net/?f=3x%2Bx%3D190000)
![4x=190000](https://tex.z-dn.net/?f=4x%3D190000)
![x=47500](https://tex.z-dn.net/?f=x%3D47500)
Salary of the president of the University =
= $142500
Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
