What is the value of x in the equation 4x - 10 = 3x?

Answers

Answer:

x = 10

Step-by-step explanation:

given

4x - 10 = 3x ( subtract 3x from both sides )

4x - 3x - 10 = 3x - 3x ( simplify both sides )

x - 10 = 0 ( add 10 to both sides )

x - 10 + 10 = 0 + 10 , that is

x = 10

A population of endangered birds decreases by 3% each year.a. If the current population is 30,000 birds, write an equation that represents the number of birds, N, in terms of the number of years, T, from the present.

b. Approximately what will the bird population be after twenty years? Round your answer to the nearest thousand.

Answers

Since the number of bird decreases 3% per year then for year 1 there will be 29 100 birds left. This value is 97% of 30000. From this the number of birds for year 1 is N = 30000(1-0.03)

A. N = 30,000 $(1-0.03)^(2)$

B. To solve this we use the equation we established in letter A. We get the answer by substituting T with 20. N = 16,000.

Answer: a) The required equation is,

$N=30000(0.97)^T$
