Answer:
d + n = 147
0.10d + 0.05n = 11.65
d = 86, n = 61
Step-by-step explanation:
Let
Number of dimes = d
Number of nickels = n
Total coins = 147
Total value = $11.65
d + n = 147 (1)
0.10d + 0.05n = 11.65 (2)
From (1)
d = 147 - n
Substitute d = 147 - n into
0.10(147 - n) + 0.05n = 11.65
14.7 - 0.10n + 0.05n = 11.65
- 0.10n + 0.05n = 11.65 - 14.7
-0.05n = -3.05
n = -3.05 / -0.05
= 61
n = 61
Substitute n = 61 into
d + 61 = 147
d = 147 - 61
d = 86

The function g is defined by:
g(x) = (4 + x) / (5 + 3x) ...(1)
Now, we need to find g(5n); that is, we make: x = 5n
Replacing this into equation (1):
g(5n) = (4 + 5n) / (5 + 3*(5n)) = (4 + 5n) / (5 + 15n)
So, the final answer is:
g(5n) = (4 + 5n) / (5 + 15n)

then KD would be equal?
not sure, but try that
