Let's use the furthest left point on the triangle to figure out the translation.
Blue triangle = (-5,1)
Black triangle = (-3,-1)
To get from -5 to -3 we moved the triangle 2 units to the right, which means that we added 2.
To get from 1 to -1, we moved the triangle 2 units down, which means we subtracted 2.
Rule: {2, -2}
Hope this helps!
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:
-1/3
Step-by-step explanation:
Step 1. Simplify setup.
12/x - 6 = 18/x - 4
Step 2.Subtract 12/x from both sides.
-6 = 6/x - 4
Step 3. Add 4 to both sides.
-2 = 6/x
Step 4. Divide it all by 6 to leave X alone.
-1/3 = x
So X equals to -1/3.
