Answer:
Step-by-step explanation:
Pythagoras theorem
a^2=b^2+c^2
(x-2)^2=9^2+(x+1)^2
x^2-4x+4=81+x^2+2x+1
Collect like terms
-4x-2x=82-4
-6x=78
x=-13
It would be 1531600
How I did it
First I divided the percentage by 100. Example >> 0.6/100= 0.006
Then I took 2002 population >> 1522475 + 0.006 x 1522475 = 1531609.85
Write an equation like this...
4 - 6x = 40
x = -6
Check:
4 - (6 x -6)
4 - (-36)
* A "-" symbol and "-" symbol equal a "+" sign
So...
4 + 36 = 40
Hope this helps! :3
The first one

Answer: 625
Step-by-step explanation:
Let x be the total number of readers have newspaper.
Given: 8% of x = 50
Since 8% = 0.08 [we divide percent by 100yo convert it in decimal ]
So, 0.08x =50
Hence, the total number of readers have newspaper = 625
