in 2001,there were g white storks migrating fron europe to africa in winter.The next year, only half of the white storks made the journey to africa.in 2003,the number of migrating white storks decreased by another 45.
(a) find the number of white storks that migrated in 2003 in terms of g.
(b) if the number of white storks that migrated in 2001 was 1800,how many white storks migrated in 2003?
2001 white storks = g
2002 white storks = g/2
2003 white storks = g/2 - 45
A.) g/2 - 45
B.) g/2 - 45
Substitute 1800 to g
= 1800/2 - 45
= if not same denominator, you must multiply whole number to denominator then add to numerator then divide back to the denominator. Like this:
= 45 x 2
= 100
= 100 + 1800
= 1900
= 1900/2
= 950
There are 950 white storks migrating in 2003.
To solve this problem, let's break it down step by step.
(a) To find the number of white storks that migrated in 2003 in terms of g, we need to consider the decrease in the number of storks each year.
In 2001, there were g white storks migrating to Africa.
In 2002, only half of the storks made the journey, so the number of storks migrating to Africa in 2002 would be (1/2)g.
In 2003, the number of migrating white storks decreased by another 45, meaning the number of storks would be (1/2)g - 45.
So, the number of white storks that migrated in 2003 in terms of g would be (1/2)g - 45.
(b) If the number of white storks that migrated in 2001 was 1800, we can substitute this value into the equation from part (a) to find the number of white storks that migrated in 2003.
Let's replace g with 1800 in the equation: (1/2)(1800) - 45.
Calculating this, we get:
(1/2)(1800) - 45 = 900 - 45 = 855.
So, if the number of white storks that migrated in 2001 was 1800, the number of white storks that migrated in 2003 would be 855.
