Javon's first 3 quizzes had a mean score of 90%. If he scores 46% on his next quiz, what will be his mean quiz score for these 4 quizzes?

79%

Step-by-step explanation:

Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:

= 90% × 3

= 270%

Since he scores 46% on his next quiz, we add it to the previous score and this will be:

= 270 + 46

= 316

Then, his mean quiz score for these 4 quizzes will be:

= Total score / Number of quizzes

= 316 / 4

= 79%

79%

Step-by-step explanation:

316 / 4 = 79%

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
