Answer: the winning strategy is to take 1 chip, leaving our opponent with  the losing position of 5 chips.

Step-by-step explanation:

suppose we start with 6 chips.

* If we take 1 chip, we leave our opponent with 5 - which we showed  

  was a losing position for him.

* If we take 2 chip (leaving 4), our opponent will take 3 - we lose.

* If we take 3 chip (leaving 3), our opponent will take 2 - we lose.

So our winning strategy is to take 1 chip, leaving our opponent with  

the losing position of 5 chips.

.Resolva as equações, sendo U = Q (separe as respostas por vírgulas). A) 3y - 2 = - y + 4 B) 5 - 4x = x + 3 + 2x C) - 12 - 9x =
Oxana [17]

Answer:

(A) y=1.5

(B)x=\dfrac27

(C)x=2\dfrac23

(D)x=-5.25

Step-by-step explanation:

(A)

3y - 2 = - y + 4\\3y+y=4+2\\4y=6\\y=\dfrac64\\\\y=1.5

(B)

5 - 4x = x + 3 + 2x\\5 - 4x = 3 +3x\\5-3=3x+4x\\7x=2\\x=\dfrac27

(C)

-12 - 9x = - 4 - 12x\\-9x+12x=-4+12\\3x=8\\x=\dfrac83\\\\x=2\dfrac23

(D)- x - 6 + 3x = -2x + 8x + 15

2x-6 = 6x + 15\\2x-6x=15+6\\-4x=21\\x=\dfrac{21}{-4} \\\\x=-5.25

horsena [70]

Answer:

FGE = 180 - (14 + 78)°

= 88°

so angle GEC = 88°

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 92/4

= 23
