Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:

, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
The answer is 3. If you find the unit rate of white to blue paint and multiply it by 4.5 it would come out to 3.000007 or something minute like that.
Answer:
3 , 1 , -1 , -3
Step-by-step explanation:
5 - 2n
n = 1 ; 5 - 2n = 5 - 2*1 = 5 - 2 = 3
n = 2; 5 - 2n = 5 - 2*2 = 5 - 4 = 1
n = 3; 5 - 2n = 5 - 2*3 = 5 - 6 = -1
n = 4; 5 -2n = 5 - 2*4 = 5 - 8 = -3
First 4 terms are : 3 , 1 , -1 , -3
Answer:
x = 1, y = 3
x = -5, y = -3
