y=2;x=3

Step-by-step explanation:

multiply first equation by -2 and the second equation by 3

-6x+4y=-10

6x+21y=60

      25y= 50

           y=2

sub y=2 in one of the original equations

3x-2(2)=5

3x=9 (add 4 to 5)

x=3.

I truly hope my answer helped.

5

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
