Iwill give brainliest to the best answer to this question: each year, the department of water works measures the chloride concentration level in the water. the first year, they found the chloride concentration changed by −135 mg/l . it is estimated that the chloride concentration will change −2115 mg/l the next year. what is the total change that will likely occur in 2 years? enter your answer as a simplified mixed number in the box. /l

The answer is for sure           - 3  2/3

the two  goes on top of the three

The total change that will likely occur in 2 years is mg/L        

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by mg/L .

It is estimated that the chloride concentration will change mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by mg/L in first year.

The chloride concentration will change mg/L the next year.

The total change that will likely occur in 2 years is

In a mixed fraction - mg/L        

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
