Answer:
17.8 cm
Step-by-step explanation:
In the 17 hours between heights of 18.6 cm and 15.2 cm, the candle lost 3.4 cm in height. That is, the height decreased at the rate of ...
(-3.4 cm)/(17 h) = -0.2 cm/h
In the 4 hours between 12 hours and 16 hours of burning time, the candle will have changed its height by (4 h)(-0.2 cm/h) = -0.8 cm.
The height at 16 hours of burning is then 18.6 cm -0.8 cm = 17.8 cm.

Answer:
The answer is 3
Step-by-step explanation:
First write the equation as you see it.
-11b+7=40
Then switch the take away seven from the left side then place it in the right side but as a minus.
-11b=40-7
Next do the math on the right side.
-11b=33
Once you have done that you divide the number on right with the number on the left which leaves you with the answer.
b=-3
Hope this helped :)
