To answer the question let x be the amount of money James will have after he sees Rita. If it was him who owed Rita $12 and he intent to pay, he will have $42.80 - $12 after seeing her. However, if it was Rita who owed him the amount, the money he will have after seeing her will be $42.80 + $12. Thus, the equations are,
x = 42.80 - 12 and x = 42.80 + 12
3x*5x-2=4-2x*1
15x-2=4-2x
13x=2
x=6.5
To find the length of the wire, use the Pythagorean theorem
a^2 + b^2 = c^2
18^2 + 40^2 = c ^2
324 + 1600 = c^2
1924 = c^2
44 = c
The wire is approximately 44 feet.
