<h3>
In total Jane initially had 11 dimes.</h3>
Step-by-step explanation:
The number of cents Sam has now = 70 cents
The number of cents Jane has now = 75 cents
Initially Sam had only nickels, and Jane had only dimes.
Now, since Sam has $0.7
⇒ He holds 7 dimes.
⇒He gave away 7 nickels.
Also, Jane has $0.75
Now, 0.35 = 7 x (0.05) = 0. 05 x 7 nickels
So, Jane now has 7 nickels and 4 dimes.
Hence, in total Jane initially had 11 dimes.

Edad de María = 5 * 3 = 15 años
Explicación paso a paso:
Dejar :
Edad de Claudia = x
Edad de María = 3x
En 5 años :
3x + 5 = 2 (x + 5)
3x + 5 = 2x + 10
3x - 2x = 10-5
x = 5
Edad de Claudia = 5 años
Edad de María = 5 * 3 = 15 años
