Answer:
Therefore the ratio of home-team fan to away team fan at 8:00 p.m is
=109:67
Step-by-step explanation:
Initially , total home team fans =1000
and away team fans = 700.
7:00 pm to 8:00 pm = 1 hour = 60 minutes
Given that
Every 10 minutes the number of arrival home team fans is 15.
Then in 1 minutes the number of arrival home team fans is
and in 60 minutes the number of arrival home team fans is
=90
Therefore total home team fans = (90+1000)=1090
Given that
Every 10 minutes 5 fans leave of away team leave.
then in 1 minutes fans leave of away team leave.
and In 60 minutes =30 fans leave of away team leave.
Since 30 away team fans leave.
Total away team fans = (700-30)=670
Therefore the ratio of home-team fan to away team fan at 8:00 p.m is
=1090:670
=109:67
Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:
Now we know what <em>x</em> equals. Let's substitute this into the second equation:
We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:
Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
