Question

Omg pls help ill give you 20 points

Answer 1

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

`= 19 \frac{1}2}`

t = 19 minutes 30 seconds

After 19 1/2 minutes both tanks will have 610 liters of water
