Which operation should be performed first according to the order of operations? 44 • 2 – [(5 + 20 • 3) – 12] + 16 ÷ 2 5 + 20 20 • 3 16 ÷ 2 44 • 2

5+ 20 is the first thing that you do in the equation you  do 5+20x3 then you do minus 12 then you can solve the equation straight across. you follow the rule PEMDAS. parenthesis, exponents, multiplication, division, addition, subtraction.

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%

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
