The water level is a number that indicates whether the level is above or below normal using positive or negative values.

After a heavy storm, the water level of a stream is -2.8 feet. This level is 1/2 times 2.1 feet more than the previous water level.

What was the previous water level?

Respuesta :

Answer:

-3.85 feet

Step-by-step explanation:

-2.8 feet + 1/2(2.1) = 1.05 as the stream is more than previous then we must subtract to find previous = -2.8 - 1.05 = -3.85 feet
