(by far the most painful question all day) 226 mins = 3.77 hours 4 3/5 hours = 4.6 hours 4.6- 3.77 = 0.83 hours 0.83 hours = 49.8 mins = 2988 seconds.
Answer:
] y=x-4
-2x+y=18
y - x = -4
y - 2x = 18
equation [2] for the variable y
[2] y = 2x + 18
// Plug this in for variable y in equation [1]
[1] (2x+18) - x = -4
[1] x = -22
// Solve equation [1] for the variable x
[1] x = - 22
// By now we know this much :
y = 2x+18
x = -22
// Use the x value to solve for y
y = 2(-22)+18 = -26

Answer:
<h2>61°</h2>
Step-by-step explanation:
Use the sine law:
![\dfrac{MO}{\sin(\angle N)}=\dfrac{NM}{\sin(\angle O)}](https://tex.z-dn.net/?f=%5Cdfrac%7BMO%7D%7B%5Csin%28%5Cangle%20N%29%7D%3D%5Cdfrac%7BNM%7D%7B%5Csin%28%5Cangle%20O%29%7D)
We have:
![MO=18\\\\NM=6\\\\m\angle O=17^o\to\sin17^o\approx0.2924](https://tex.z-dn.net/?f=MO%3D18%5C%5C%5C%5CNM%3D6%5C%5C%5C%5Cm%5Cangle%20O%3D17%5Eo%5Cto%5Csin17%5Eo%5Capprox0.2924)
Substitute:
<em>cross multiply</em>
![6\sin(\angle N)=(18)(0.2924)](https://tex.z-dn.net/?f=6%5Csin%28%5Cangle%20N%29%3D%2818%29%280.2924%29)
<em>divide both sides by 6</em>
![\sin(\angle N)=0.8772\to m\angle N\approx61^o](https://tex.z-dn.net/?f=%5Csin%28%5Cangle%20N%29%3D0.8772%5Cto%20m%5Cangle%20N%5Capprox61%5Eo)
