Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
Answer:
x=-4.22222
The 2 is repeating
Step-by-step explanation:
First you subtract 18 from both sides
9x=--38
Then divide both sides by 9
x=-4.22222
The 2 is repeating
15x+40=115
15x+40-40=115-40
15x=75
15/15 x=75/15
x= 5
Answer:
1) If it is spun 250 times, it will not land on W 207 times.
2) If it is spun 100 times, it will land on N 17 times (rounded up).
3) 1 out of 6
4) It has the same answer as 1) <em>(If it is spun 250 times, it will not land on W 207 times.)</em>
Mma can see that 2.09 is closer to 2 than 2.36.
