Answer:
2
Step-by-step explanation:
First do 3 x 3 = 9 - keep this 9 to the side for now
Then do 3 x 
= 
- also keep this to the side for now
Then do 
x 3 = 
Then do x = -7
So,
9 + - 7
Therefore, 9-7 = 2
We will use B for the number of baseball cards and H for the number of hockey cards.
B = 5H
B + H = 840
Use substitution by plugging 5H in for B in the second equation.
5H + H = 840
6H = 840
H = 140
If there are 140 hockey cards, then there are 5*140 = 700 baseball cards.
So the answer is 700.
It’s B cause he is going down to the negative so he is going to the left side
A parallelogram is a kind of quadrilateral polygon composed of whose side are parallel to each other. So in your question the length of one side of the polygon which is A and B is 6 units so the D and C should also be 6 units also. An the coordinates of D is (-3,2)
