x and x+4 are the numbers
3x=2(x+4)
3x=2x+8
3x-2x=8
x=8
x+4=12
When you are rounding to the nearest tenth, you only look at the number right to the tenths which in this case is 5, so you round up the 6 to a 7, which will be.
8.7
The x values are the domain and they y values are the range. So the domain is {-2, 0, 2}. And the range is {-1, 0, 1}. So B is the answer.
Okay let's see.. 0.750
1.200
As we see 1 is bigger than 0.So that means 1/2 is bigger.Hope this helps! (;
x × 44ft =3564
× = 81
