Johnny must learn more than 90 new plays before the big game. he has already learned 4. write an inequality that represents how many more plays he needs to learn to reach his goal?

x + 4 > 90

x = the greater portion of the plays he needs to learn.

4 = the plays he's already learned

90 = less than the plays he needs to learn.

I don't know why someone would need to learn more than 90 plays but whatever.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
