Answer:
n1=1,n2=4
Step-by-step explanation:
first divide both sides by 6 of the equation
=n^2-3n=4
n^2-3n-4=0..move the constant to the outerside
n^2-3n-4=0...write -3 as a difference
n^2+n-4n-4=0
factor out n
n×(n+1)-(4n-4)=0
nx(n+1)-4(n+1)=0
(n+1)×(n-4)=0
=n(+1=0)work out
n-4=0
n=-1
n-4=0
now solve for n
and the answer will be ;n1=-1,n2=4
there's not enough information to solve
Step-by-step explanation:
In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant; that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.
<u>Angie buys</u>
1 Software package + 3 months of game play.
Each software package costs = $20.
Let us assume cost of one month of game play = $x.
Therefore, total cost to Angie for 1 Software package + 3 months of game play = 20*1 + 3x = 20 +3x.
<u> Kenny buys </u>
1 software package + 2 months of game play.
Therefore, total cost to Kenny for 1 software package + 2 months of game play = 20*1 + 2*x = 20+2x.
Their total cost = $115.
Adding their costs and set it equal to 115, we get
<h3>20 +3x + 20+2x = 115.</h3>
Now, we need to solve it for x.
40 + 5x = 115.
5x = 115 - 40.
5x = 75.
Dividing both sides by 5, we get
x= 15.
<h3>Therefore, $15 is the total cost of one month of game play.</h3>
