What is the rest of the problem? I can help you!
Answer:
16
Step-by-step explanation:
x+y=30 solve for x x=30-y
substitute x with 30-y and solve
11.25x+22.4y=515.9
11.25(30-y)+22.4y=515.9
337.5+11.15y=515.9
11.15y=178.4
y=16
since we're solving for just large candles it's 16
if need small cangle number 30-16=14
Here are some Examples: :)

is 0.2222222222 and so on

is 0.4444444444 and so on

is 0.777777777 and so on
So it could be anything like 9 or 6 as long is its like this

Answer:
86.4 km
Step-by-step explanation:
Since the cyclist travels 1.8km in a minute, he will travel 48 times that in 48 minutes:

<span>b – 2a – c
= 9 - 2(-3) - (-6)
= 9 + 6 + 6
= 21
answer
21</span>
