Answer:

Step-by-step explanation:
1) the rule of transformation [degr → rad] is:
![\alpha [rad]=\alpha [degr] *\frac{\pi }{180};](https://tex.z-dn.net/?f=%5Calpha%20%5Brad%5D%3D%5Calpha%20%5Bdegr%5D%20%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3B)
2) according to the formula above:
230°=230*π/180=23π/18 [rad].
I believe it is C, not 101% positive, but I think it is C
Answer:
51 to 6
Step-by-step explanation:
Answer: 21/56
Step-by-step explanation:
You multiply the numerators together, 3•7 equalling 21.
Then you multiply the denominators together, 7•8 equalling 56.
-2x+y=5
Multiply everything by-1
2x-y=-5
