Answer:
A. 7
Step-by-step explanation:
If you were to solve for c by using d as 7 you would get:
c+7=40
c would then equal 33, which is greater than 30
So 12=total
7=blue
black=total-blue=12-7=5
black=5
1. 2/3 of 12 were taken out or 24/3 were taken out or 8 marbles were taken out
there is not enough info becasue it doesn't specify which ones were taken out
2. there is not enough info
3. not chosen=total-chosen=12-8=4 so 4 were chosen
Answer:
B (2, 2)
Step-by-step explanation:
Given the graphs of a system of equations then the solution is at the point of intersection of the 2 lines.
That is (2,2) ← is the solution → B
I think it is the first one could be wrong tho
