Question 1123453
<br>
The length of the candle in inches after "h" hours is 9-(2/3)h.<br>
The candle is burned completely when its length is 0.<br>
So solve the equation: {{{9-(2/3)h = 0}}}.<br>
Of course, you don't need to use formal algebra.  Just find how many "2/3 of an inch" there are in 9 inches.<br>
It might sound complicated because of the fraction.  But it's the same kind of calculation as if the candle were 14 inches long and burning at a rate of 2 inches per hour: (14 inches) divided by (2 inches per hour) = 7 hours.<br>
(9 inches) divided by (2/3 inch per hour) = ?? hours.
