Answer:
Step-by-step explanation:
Amount of water in tank 1 = amount of water in tank 2
30t +25 = -20t + 1000
Add 20t to both sides
30t + 20t + 25 = -20t + 20t + 1000
50t + 25 = 1000
Subtract 25 from both sides
50t + 25 - 25 = 1000 - 25
50t = 975
Divide both sides by 50
t = 975/50 = 39/2
t = 19 minutes 30 seconds
After 19 1/2 minutes both tanks will have 610 liters of water

Step-by-step explanation:
using pemdas, do the exponent first
6-2=4
then multiply by 4
4x4 is 16
add 3^2 to this, which = 9
so 16+9-6 is on top which equals 19, this is over 3
so 19/3
