Help pls 6th grade math (look at the pic attached) btw it’s 2 questions

1. s=7

2 s = 8

Step-by-step explanation:

s + 12 =19 you subtract 12 from 19 and you get 7 so you rewrite it like this s = 7 then divide s by 7 and get s = 7

s - 6=2 add 6 to both sides so 6+2 equals 8

s=8

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%
