Stingray population of particular reef is decreasing at a rate of 1.4% per year the population was 3800 and the year 2008 what is the best prediction for the population in the year 2013 round to nearest whole number

4074

Step-by-step explanation:

This is compound increase problem that can be solved with the formula:

Where

F is the Future amount [amount we want for 2013]

P is the present amount [in 2008, it is 3800 So P = 3800]

r is the rate of increase [1.4% per year in decimal would be 0.014]

t is the number of years [ 2008 - 2013 is 5 years]

Now plugging all the information into the formula we have:

ROunding to nearest whole number that would be 4074

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
