Answer:
x + 8
Step-by-step explanation:
Answer:
$50.08
Step-by-step explanation:
Let's use x to represent the lesser expensive hat and 2x to represent the more expensive hat since the more expensive hat is twice the price.
So, our equation would be 2x + x = 75.12
We can combine them together to make 3x.
Then, we make the 3x equal to 75.12
3x = 75.12
Now, we solve it.
Divide both sides by 3 to solve for x.
75.12/3 = 25.04
x = 25.04
Lastly, plug it in for 2x to get the price of the more expensive hat.
2(25.04) = ?
2(25.04) = 50.08
Therefore, the price of the more expensive hat is $50.08
Answer:
x=25/64
Step-by-step explanation:

Step-by-step explanation:
Given

Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD

For AB:


So:





For CD:


So:




For Lines to be parallel, the slope must be equal:
i.e. 
This condition is not true because:

For Lines to be perpendicular, the slope must be:

This implies:



<em>Hence, the lines are perpendicular</em>
