Meredith is solving the equation 7x + 3(x−2) = 14. Her first step is shown as 7x + 3x − 6 = 14 . Which property did Meredith apply in her first step?

Can i get some on 18,20,& 22? or one of them

Give me the equations of two lines that have the same slope but are not parallel.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
