A:
Answer:To solve, use a simple one-step equationKnown: Number of coins; Number of Nickles. Unknown: Number of Dimes.a) To find the number of Dimes b) Use x (or virtually any letter) to represent the unknown number of dimes c) 9+x=13 d) Subtract 9 from both sides to cancel out the 9 and isolate the variable on one side. x=4e) 9+4=13, so yes, the answer is correct
