It’s the second one, cuz that’s the correct formula and equation
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.
hope this helps :))
4 dimes=4 *10=40 cents
2.25-0.40=1.85

185=5 times number of nickels
divide both sides by 5
37=number of nickles
has 37 nickles
