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.

Answer:
(f+g)(x) = 2x-3
(k+g)(x) = 3x-3
(f-k)(x) = -x
(k-g)(x) = x+3
Step-by-step explanation:
(f+g)(x)
x + x - 3
2x - 3
(k+g)(x)
2x + x - 3
3x - 3
(f-k)(x)
x - (2x)
-x
(k-g)(x)
2x - (x - 3)
2x - x + 3
x + 3
