NO, THE ANSWER IS NOT 40.

The solution to the problem is as follows:

If they vary directly, their ratio is always equal to the same number.
Since 10/2 = 5, any p/q has to = 5.
<span>So p/20 = 5
</span>
<span>p = 5 x 20 = 100

A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour. a blue cans is 6 inches tall and burns at a rate of 1/5

Galina-37 [17]

Let t = number of hours

The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t

The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t

You want the lengths to be equal, so the equation is

8 - (7/10)t = 6 - (1/5)t
