Answer && Step-by-step explanation:
7 yards == 4/4
by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it
7 => 6*1/4
6*1/4=>5*2/4
5*2/4=>4*3/4
4*3/4=>4
4=> 3*1/4
3*1/4=>2*2/4
2*2/4=>1*3/4
1*3/4=>1
1=>1/4
1/4 remains and 9 bows were made
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:
(4,8)
Step-by-step explanation:
6x-4y=-8
11x+4y=76 eliminate y
6x+11y=-8+76
17 x=68
x=68/17=4
substitute x :
6x-4y=-8
6(4)-4y=-8
-4y=-8-24
y=-32/-4
y=8
