X + y= 30
.05x + .10y= 1.65
n + d = 30
5n + 10d = 165
-5n - 5d = -150
5n + 10d = 165
5d = 15
d = 3 dimes
n + 3 = 30
n= 27 nickels
Well we need the problem or else we cant help you.

Answer:
The square root of 179 rounded up to 7 decimal places is 13.3790882. It is the positive solution of the equation x² = 179.
Use the Pythagorean Theorem.
The length of the path is d, and it is the hypotenuse of the right triangle.
50^2 + 120^2 = d^2
2500 + 14400 = d^2
d^2 = 16900
d = 130
Answer: 130 m
