Answer:
Step-by-step explanation:
22.75
N=8+d
10d+5n=145
divide 2nd equaiton by 5 to make nicer and easier
2d+n=29
subsitute 8+d for n in 2nd equation
2d+8+d=29
3d+8=29
minus 8 both sides
3d=21
divide by 3
d=7
sub back
n=8+d
n=8+7
n=15
15 nickles and 7 dimes

Answer:
about 0.0143 microfarads
Step-by-step explanation:
The effective capacitance of capacitors in series is the reciprocal of the sum of their reciprocals:
1/(1/0.02 +1/0.05) = 1/(50+20) = 1/70 ≈ 0.0143 . . . microfarads
Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
