Q. aIf Tom has 9x 9 x baseball cards, Adam has 1313 more than Tom, and Dave has 2y 2 y baseball cards, together they would have how many cards?\newlineA. 9x+2y+13 9 x+2 y+13 \newlineB. 18xy+13 18 x y+13 \newlineC. 18xy+2y 18 x y+2 y \newlineD. 18x+2y+13 18 x+2 y+13
  1. Tom's Baseball Cards: Tom has 9x9x baseball cards. This is given in the problem statement.
  2. Adam's Baseball Cards: Adam has 1313 more than Tom. To find the number of baseball cards Adam has, we add 1313 to the number of cards Tom has.\newlineAdam's cards = Tom's cards + 1313\newlineAdam's cards = 9x+139x + 13
  3. Dave's Baseball Cards: Dave has 2y2y baseball cards. This is given in the problem statement.
  4. Total Cards Calculation: To find the total number of cards they have together, we add the number of cards each person has.\newlineTotal cards = Tom's cards + Adam's cards + Dave's cards\newlineTotal cards = 9x+(9x+13)+2y9x + (9x + 13) + 2y
  5. Simplify Expression: Simplify the expression by combining like terms.\newlineTotal cards = 9x+9x+13+2y9x + 9x + 13 + 2y\newlineTotal cards = 18x+2y+1318x + 2y + 13
