Answer:
1300
Step-by-step explanation:
Let the amount put in the station's tank = x
4(400 + x) = 8100 - x Remove the brackets
1600 + 4x = 8100 - x Subtract 1600 from both sides
1600 - 1600 + 4x = 8100 - 1600 - x Do the subtraction
4x = 6500 - x Add x to both sides
4x + x = 6500 - x + x
5x = 6500 Divide by 5
5x/5 = 6500/5
x = 1300
1300 gallons were added to the station's tank.

Answer:
13 inches
Step-by-step explanation:
To find the greatest number of inches possible in the length of each piece, we need to find the greatest common divisor of 39, 52 and 65.
So, the divisors of 39 are: 1, 3 and 13
The divisors of 52 are: 1, 2, 4, 13 and 26
The divisors of 65 are: 1, 5 and 13
Therefore, the common divisors are 1 and 13. Finally the greatest common divisor is 13. It means that the greatest number of inches possible in the length of each piece is 13 inches.
