The height of the candles when they first burn down to the same height is 10 cm
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let y represent the height of the candle after x hours.
For the first candle:
y = -(5/6)x + 15
For the second candle:
y = -(5/2)x + 25
To have the same height:
-(5/6)x + 15 = -(5/2)x + 25
x = 6 hours
y = -(5/2)(6) + 25 = 10 cm
The height of the candles when they first burn down to the same height is 10 cm

Answer for the first dropdown box is CAF and EFH
Answer for the second dropdown box is because they are corresponding angles of parallel lines cut by a transversal
Answer for the third dropdown box is transitive property of congruence
------------------------------------------------------------------------------
Explanation:
Angles CAF and EFH are corresponding angles because they are on the bottom side of the parallel lines, and on the right side as well. So they are congruent (due to the lines being parallel).
Since CAF = EFH and EFH = HFD, this means that CAF = HFD
It's similar to saying if x = y and y = z, then x = z. Think of it as a connecting chain. This is the transitive property.
It’s the letter c
40>36=4% 94%-4%=90
That'd take 3.75 minutes, about 4 minutes.
