Answer:

1st = 22

2nd = 24

3rd = 26

Step-by-step explanation:

1st = x

2nd = x +2

3rd = x + 4

6(x + x + 4) = 24 + 11(x + 2)

6(2x + 4) = 24 + 11x + 22

12x + 24 = 46 + 11x

x + 24 = 46

x = 22

x + 2 = 24

x + 4 = 26

g100num [7]

Answer:

<u><em>3.5 °C</em></u>

Step-by-step explanation:

To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.

3 x 7 = 21

Add 21 and 8 together to get the sum of the temperatures in the first 8 days.

21 + 8 =29

Divide 29 by 8 to get the mean temperature for the first eight days.

29 ÷ 8 = 3.5
