Answer:Allen is correct
Step-by-step explanation: Allen is correct because angle 2 has more information than angle 1 and angle 1 is only 30 degrees.
Y = 4 - x
3x + 4(4-x) = 14
3x + 16 -4x = 14
-x = -2
x = 2
y = 2
Answer:
We have the equation
![a+x= 1+xa^2](https://tex.z-dn.net/?f=a%2Bx%3D%201%2Bxa%5E2)
we leave the terms with x on the left side of the equation and the independent terms on the right side.
![x-xa^2=1-a\\(1-a^2)x=1-a\\](https://tex.z-dn.net/?f=x-xa%5E2%3D1-a%5C%5C%281-a%5E2%29x%3D1-a%5C%5C)
resolving for x we have that
![x=\frac{1-a}{1-a^2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1-a%7D%7B1-a%5E2%7D)
Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when ![1-a^2=0\\1=a^2\\a=\pm1](https://tex.z-dn.net/?f=1-a%5E2%3D0%5C%5C1%3Da%5E2%5C%5Ca%3D%5Cpm1)
Then, for
the equation hasn't solution
Answer:
$7.25
Step-by-step explanation:
Total amount spent on the ticket = $40.75
Number of ticket purchased = 5
Processing fee per ticket = $0.90
Unknown:
Cost of each ticket = ?
Solution:
To solve this problem, we need to find the processing fee for the 5 tickets purchase;
Processing fee = number ticket x processing fee per ticket
Processing fee = 5 x 0.9 = $4.5
Now, the real cost a ticket = $40.75 - $4.5 = $36.25
So, cost per ticket is;
Cost =
= $7.25
