If you are looking for the median number, it would be the number in the middle which is 50
2(x-3)+9=3(x+1)+x
2x-6+9=3x+3+x
2x+3=4x+3
-2x -2x
3=2x+3
-3 -3
0=2x
x=0
27 divided by 9 is 3
We can check that by multiply 3 and 9 and we get 27
Hope this helps!
Since the properties of a rhombus tells us that both pairs of opposite sides are congruent we can therefore conclude that DB will be 12
Subtract -2 and -1 which means add because there both negative which gives you -3 then 5-7 which is -2 so your slope is -3 over -2
