Question

Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original height every hour.
Please complete the following sentence by writing the number in the blank. Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.

Candle looses 10% of 8 inches, it equals:

8*0.1 = 0.8 inches an hour

Let x be required time, then:

8 - 0.8x > 7
0.8x < 8 - 7
0.8x < 1
x < 1/0.8
x < 1.25

Solve the following equation for x

cupoosta [38]

Hi there!

$5( - 3x - 2) - (x - 3) = - 4(4x + 5) + 13$

First we want to get rid of the parentheses.
$- 15x - 10 - x + 3 = - 16x - 20 + 13$

Now we collect terms on both sides of the equation
$- 16x - 7 = - 16x - 7$

Since both sides of the equation are the same, every number is a correct solution to this equation. (Whatever number you choose to fill in will be correct).
