Answer:
x= 9/20 = .45
Step-by-step explanation:
20x=9
x= 9/20 = .45
The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi. (x,y) has the meaning of a plane's vector from origin of coordinates.
If
is a number that is both divisible by 4 and 5, then

4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that
is a solution to the system, where
is any integer. Simply put, any multiple of 20 fits the bill.
Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have
when
, so the sum we want to compute is

Answer:
Subtract 2x from each side, Subtraction Property
Step-by-step explanation:
Plug in the values of x and y into each ineqaulity and see which one fits
You'll find it is d
