During a drought, the water level of a lake changes -1 1/3 ft. pwr day. write and solve an equation to find out how long it takes for the water level to change -16 ft.

It takes 12 days for the water level to change -16 feet

Solution:

Given that  

During a drought, the water level of a lake changes feet per day.

Let assume number of days required for change of water level to -16ft = "x"

So change of water level in "x" days is:

As we assumed that change in “x” days in water level = -16feet

Hence it takes 12 days for the water level to change -16 feet

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
