The first step would be to add 7 to both sides.
3n-7=30
add 7
3n=37
divide by 3
n=12.33
Step-by-step explanation:
the slope is the ratio of "y coordinate difference / x coordinate difference".
so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.
(-1, -1) and (0, -7)
x changes by +1 (from -1 to 0).
y changes by -6 (from -1 to -7).
so, the slope is -6/1 = -6.
D is the right answer.
If there are 12 shirts total and three of them were green, it would be 3 out of 12 or 3/12. Hope this helps! :)
Answer:
You can use tree diagrams to find the probability of something
17 pieces. She had two and she had to have 15 to give to the children. If each child got 3 and there is 5. This turns into 3*5=15. Then you would add 15+2 to get 17
