Mathematics

DENIUS [597]3 years ago
8 0

Step-by-step explanation:

8.

1/2(x + 24) = 21

1/2x +12 = 21

1/2x = 9

x = 18

9.

28 - 3x - 4 = 2x + 12 + x

24 - 3x = 3x + 12

24 - 6x = 12

-6x = -12

x = 2

10.

3x - 18 + 6 = 5x - 6

3x - 12 = 5x - 6

-2x - 12 = -6

-2x = 6

x = -3

hope it help.

Answer please have 20 questions? will give the brilest.

To find the mean of a dot plot, add up all of the data and divide by how many numbers there are. 

In this case, the data added up is 4 + (5 x 4) + (6 x 3) + (7 x 2) + 10

4 + (5 x 4) + (6 x 3) + (7 x 2) + 10 = 66

With this information, we can now find the mean. 
66/11=6

Therefore, the mean is 6. Hope this helps! Feel free to ask any questions.
