A. 4.18
B. 8.36
For the first one
Answer:
x > 2
Step-by-step explanation:
-1/2x + 6 < 4x - 3
Start by adding 1/2x to both sides to get both x's on the same side
6 < 4 1/2x - 3
Add 3 to both sides to keep the x's by themselves on one side
9 < 4 1/2x
Divide both sides by 4 1/2 to get x by itself
2 < x so x > 2

Answer:
- 1.25 hours or 1 hour and 15 minutes
Step-by-step explanation:
<em>Question</em>
- <em>Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original height every hour. </em>
- <em>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.</em>
<u>Candle looses 10% of 8 inches, it equals:</u>
- 8*0.1 = 0.8 inches an hour
<u>Let x be required time, then:</u>
- 8 - 0.8x > 7
- 0.8x < 8 - 7
- 0.8x < 1
- x < 1/0.8
- x < 1.25
- or 1 hour 15 minutes
