Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
Hope this helped you! :)
(9,-5) times 2.5 is (22.5,-12.5)
The answer is (22.5,-12.5)
Hope this helps!
All you have to do is plug in.
x = 1 , y= 8
3x+5=y
3(1) + 5 = 8
3+5 = 8
8=8
They are both equal, yes. The coordinates work out in the equation. Both sides are equal so the coordinates work. The answer is yes.
Answer:
5 meters
Step-by-step explanation:
because 100 meters divided by the base equals the Height so 100 divided by 20 = 5
