Answer:
It will take 18 hours to burn a 45 cm long candle.
Step-by-step explanation:
45 cm ÷ 15 cm = 3
3 × 6 = 18 hours
— based on my knowledge
18
10 tests = x tests
/ 5 weeks = / 9 weeks
10* 9= x5
90/5= 18
The median is 20.
When lined from least to most (15, 20, 20, 22, 25) 20 is the middle number.
