Ответ:
There are 19 dimes and 95 nickels
Step-by-step explanation:
Represent the numbers of nickels and dimes by n and d. Then n = 5d.
The value of the nickels is $0.05n and that of the dimes is $0.10d. Together these two amounts come to $6.65:
$0.05n + $0.10d = $6.65.
But n = 5d.
Substituting 5d for n, we get:
$0.05(5d) + $0.10d = $6.65
Combining the two terms on the left, we get:
0.25d + 0.10d = 6.65, or
0.35d = 6.65.
Solving for d, we get d = 6.65/0.35, or d = 19. Since n = 5d, n = 5(19) = 95.
There are 19 dimes and 95 nickels.
Ответ:
95 nickels 19 dimes
Step-by-step explanation:
d=dimes
5d=nickels
0.05(5d) + 0.10(d) = 6.65
0.25d + 0.10d = 6.65
0.35d=6.65
Divide by 0.35
d= 19 (19 coins)
19 dimes =$1.9
6.65-1.9= $4.75
Nickels=$4.75
4.75/0.05 = 95 coins
19*5=95
114 coins in total
19*0.10 = 1.9
95*0.05=4.74
4.75+1.9= 6.65
