Answer:
Step-by-step explanation:
Scale= length on drawing / actual length
Let the actual length b x
3:10=2/5/x
3/10=2/5x
Cross multiply
15x=20
x=4/3
The actual length is 4/3
The answer is C if it was multiple choice
Answer:
Step-by-step explanation:
If all were dimes, the total would be $1.30. It is $0.75 more than that.

$0.75/$0.15 = 5
quarters.
Kevin has 8 dimes and 5 quarters in change.
