Hey!
The area of the board is 60,000 centimeters.
1 meter = 100 centimeters
2 meters = 200 centimeters
3 meters = 300 centimeters
Area = length × width
300 × 200 = 60,000
One cup covers 1,000 centimeters. To cover 60,000 centimeters, divide 60,000 by 1,000.
That means Arella needs 60 cups

Answer:
1.42 hours
Step-by-step explanation:
In this case we must take into account that the speed would be to fill a pool for a time, that this case is in hours, therefore it would be like this:
1/5 for the first pipe
1/2 for the second pipe
Now, we will use both at the same time, therefore:
1/5 + 1/2 = 1 / x
0.7 = 1 / x
x = 1 / 0.7
x = 1.42
That is to say that if we use both we will take a total of 1.42 hours
1. x= 8
2. x=2
3. x=-9
4. x=4
5. x= -5
6. x=16
7 x=0
8: x=-3
Hope this helps!
Answer:
The answer is the first one. Inside the absolute value symbols it is negative but absolute value answers are always positive. Instead of -30 the answer is 30.
