Question

A candle is 6 inches tall and burns at a rate of one half an inch per hour. Write an equation to represent the situation.

Answer 1

6=1/2h where 6 is the total hight, 1/2 is the rate of decrease, and h is the amount of hours the candle is burned.

Answer 2

Answer: $y=6-0.5x$

Step-by-step explanation:

Given  : The initial height of candle = 6 inches

Amount of candle burn each hour = one half an inch per hour.

$=\dfrac{1}{2}\text{ inch per hour}$

Now , the height of candle = ( initial height ) -( Rate of burning) (Numb er of hours)

Let y be the height of the candle after x hours.

Then, the equation to represent the situation will be :

$y=6-\dfrac{1}{2}x\\\\\Rightarrow\ y=6-0.5x$
