Answer:
Total number of people in the stadium = 520
Step-by-step explanation:
Let the total number of people in the stadium = x
Since, 25% of the fans are teenagers, number of teenagers in the stadium
= 25% of x
= ![\frac{25}{100}\times x](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B100%7D%5Ctimes%20x)
= 0,25x
If the number of teenagers in the stadium = 130
0.25x = 130
x = ![\frac{130}{0.25}](https://tex.z-dn.net/?f=%5Cfrac%7B130%7D%7B0.25%7D)
x = 520
Therefore, total number of fans in the stadium = 520.

P = √5.2 ^3
P = √5.2 × 5.2 × 5.2
P = √140.608 (plug into calculator)
P = 11.857824421
P = 11.86
The orbital period of Jupiter is 11.86 Earth years.

Answer:
-3/4
Step-by-step explanation:
We can find the slope by using 2 points
(0,1) and (4,-2)
m = (y2-y1)/(x2-x1)
m = (-2 -1)/(4-0)
= -3/4
You can use substitution here. First, get y alone:
14x + y = -4
subtract 14x from each side
y = -4 - 14x
Then, plug y into the second equation
-4 - 14x = 3x² - 11x - 4
then solve from there
Hope this helps :)
