Answer 1

Answer:

To solve, use a simple one-step equation

Known: 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=4

e) 9+4=13, so yes, the answer is correct

Answer 2

A. How many dimes is there out of the 13 coins.
B. D= dimes
C. 9+d=13
D. 9+d=13
Subtract 9 from 13
13-9=4
D=4
9+4=13
