Answer:
4.5 It doesn't come out evenly, but cross products do work.
Step-by-step explanation:
She is not correct.
50 * x = 3 * 75 Combine the right
50x = 225 Divide by 50
x = 225/50
x = 4.5
30
10b/a
b = 6
a =2
10(6)/2
10x6 / 2 = 60/2
= 30
There are infinitely many solutions.
Algebraically, we can eliminate and try to solve for :
Then
which is the equation of an ellipse.
