Answer:
x = # of 5 cent coins
y = # of 50 cent coins
x+y=25
.05x+.5y=7.1
y=25-x
(.05x+.5(25-x)=7.1)100
5x+50(25-x)=710
5x+1250-50x=710
-45x=-540
x=12
You have 12, 5 cent coins and 13, 50 cent coins.
Answer: 110.2 seconds
Step-by-step explanation:
Divide 1.9 by 7. That gets you 0.271428571428571. Then multiply that by 406. That in turn gets you 110.2 seconds. Alternatively, you could divide 406 by 7 and then multiply that answer by 1.9 to get the same answer.
