Answer:

y=4  x=2

Step-by-step explanation:

y=2x ⇒ I

y=10x-16 ⇒ II

y/2=2x/2

x=y/2 OR 1/2(y)

substitute I in II

y=10(y/2)-16

y=5y-16

SWAP -16 AND y

5y-y=16

4y/4=16/4

y=4

y=2x

(4)/2=2x/2

x=2

You would first plug in y to the other equation. It doesn’t matter which one you do. So it would look like...
2x=10x-16
Then you would move the like terms to one side
2x-10x=-16
-8x = 16
Then make the x alone by dividing -8 on both sides to solve for x.
X= 16/-8
x = -2
Hope this helped!

r-ruslan [8.4K]

Answer:   \dfrac{5}{9}

Step-by-step explanation:

When we throw a die , Total outcomes =6

When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]

Given : Three fair dice are rolled, one red, one green and one blue.

Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed

By Permutations , the number of favorable outcomes = ^6P_3=\dfrac{6!}{(6-3)!}=\dfrac{6!}{3!}=6\times5\times4=120

The probability that the upturned faces of the three dice are all of different numbers = \dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}

=\dfrac{120}{216}=\dfrac{5}{9}

The probability that the upturned faces of the three dice are all of different numbers  is \dfrac{5}{9} .
