Translating this word problem into an algebraic equation, we get:
3x - 2/5 = 8/5.
Let's combine the constants: adding 2/5 to both sides of this equation yields
3x = 10/5, or 3x = 2.
Solving for x: x = 2/3
Answer:
20%
Step-by-step explanation:
Since the total amount of water is 2.5 million
And 2 million evaporated,
To determine the amount left,it will be total amount- evaporated
2.5-2=0.5
To determine the% of evaporated water
It will be evaporated/total amount ×100
0.5/2.5 × 100
50/2.5
20%
So the percentage of the evaporated water is 20%
25 % of the water had evaporated.
