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
There is no such thing as subtraction. Just something to think about :)
There are numbers and there is an operation called addition. Every number has an additive inverse, an opposite value.
Example: The opposite of 4 is -4.
When we do addition between numbers like 5 and the inverse of 2: 5 + -2 this is usually what we're thinking of when we talk about subtraction. We could write it as 5 - 2.
But anyway, to answer your question,
Subtraction and division are derived from the principle operations of ADDITION and MULTIPLICATION.
Answer:
<h3>
A Geometric sequence with common ratio 3</h3>
Step-by-step explanation:
A sequence of number is called Geometric sequence if the first number is being multiplied with a constant to get the rest of the numbers
ratio between 2 adjacent numbers in a sequence will be a constant and is called common ratio.
in the given sequence the ratio between any pair of adjacent numbers is 3.
∵ this is a geometric sequence with common ratio 3
