Answer:
-7
Step-by-step explanation:
Answer:
91
Step-by-step explanation:
We know that, the sum of the exterior angles of a polygon is 360 i.e., (x+3) + (2x+1) +(3x-1) = 360 i.e., x+2x+3x+3+1-4 = 360 i.e., 6x = 360 Therefore, x = 60 Now, x+3 = 60+3 =63 2x+1 = 2*60 +1 =120 + 1 = 121 3x-4 = 3*60 - 4 = 180 - 4 = 176 The exterior angles are 63, 121 and 176
Well, what you need to figure out is what times 9 is 63. That would be 7. So n=7 :)
X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.
