The answer is 3:2. That is the answer.
The greatest common factor between 64 and 24 is 8
Let's divide both terms in the expression by 8 and leave the expression in parenthesis...
Like this!
64x -24

8x - 3
Leave 8 we divided outside the parenthesis
Now we have this!
8( 8x - 3)
This is the distributive property form!
(5,-1) is located in quadrant IV......quadrant IV has (+ x, -y).....so any points that have (+ x, - y) are in this quadrant.
Example : (6,-3) is in this quadrant......(2,-4) is also in this quadrant.
So whoever has the house with (+ x, -y) is going to be in the same quadrant as the community center.
X and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.
18=6*3 hence when y=18,x=9*3=27
x=27
