is the number of ways of distinctly arranging two objects taken from a pool of three total objects.

Step-by-step explanation:
Almons:walnuts:rasins=1:2:3
x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute
12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins
1/3 pound walnuts
2/3 pound almonds
1 pound rasins
Answer:
300
Step-by-step explanation:
30+30+w+x+y+z = 360 (all angles round a point add up to 360)
Simplifying :
60 + w+x+y+z = 360
Subtracting 60 from both sides :
w+x+y+z = 300
