Answer: 85 baseball cards
Explanation: If Doug has 5 baseball cards for every four football cards, that means he has 125%, or 1.25x as many baseball cards as basketball cards at any given moment. If he has 68, we can multiply 68 by 1.25 and get 85 baseball cards
30. Set up a proportion of 6/2 and x/10. cross multiply 6 times 10 and you get 60. divide 60 by 2=30
Sole for f by simplifying both sides of the equation then isolating the variable so that means f=-40 over 3 for number one
for the second equation you do the same thing you did for number one and the answer will be
b=8
