Answer: 144 minutes
Step-by-step explanation:
Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.
Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.
Therefore,
1/x + 3/x = 1/36
4/x = 1/36
x = 36 × 4
x = 144
The number of minutes taken by the slower pipe will be 144 minutes.
Answer: Option 'E' is correct.
Step-by-step explanation:
Since we have given that
If the length of one piece of rope is 2.8 meters shorter than the length of the other.
Let the length of first piece be 'x'.
Let the length of second piece be 'x-2.8'
Total length of rope = 20.6
So, According to question, it becomes,

So, the greatest number of the length of part of rope is 11.7 m.
Hence, Option 'E' is correct.
Answer:
-2g+3
Step-by-step explanation:
-4g + 8 - 5 + 2g
= (-4g+2g) +(8-5)
= (2-4)g + 3
= -2g +3
This equation is simplified as you can't solve it further
11.9
i just got it right on a quiz so yeah
