Answer:
Step-by-step explanation:
Step 1: Add the numbers.
20.25 can also be expressed as 
, because 
= 
= . So if we add and 11, we would get 
Step 2: Solve
- Subtract the whole numbers
This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.
LCM
Therefore, the simplified expression to this is .

9 - c = -13
-c = -13 - 9
-c = - 22
c = 22 <===
(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.
-10x-10 = -3x+4
+3x +3x
————————
-7x-10 = 4
+10 +10
————————
-7x = 14
then divide -7 on both side of the equal sign
you’ll get x=-2
then plug in -2 as x into one of the equations ( it doesn’t matter which one)
y= -10(-2)-10 = 20-10= 10
so y=10
