If you would like to simplify <span>(-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:
</span><span>(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21
6x - 2 = 2 * (3x - 1)
The correct result would be - 21 and </span><span>2 * (3x - 1).</span>
Answer:
C. The bottom answer.
Step-by-step explanation:
Answer: 3.25°C
Step-by-step explanation:
From the question, we are given the information that the mean temperature for the first 7 days in January was 3 °C. This means that the total temperature for the first 7 days in January was:
= 3°C × 7
= 21°C
We are also told that the temperature on the 8th day was 5°C. To calculate the the mean temperature for the first 8 days in January, we add the total temperature for the 8 days and then divide by 8.
The total temperature for the 8 days will be: = 21°C + 5°C = 26°C.
The mean temperature for the first 8 days in January will now be:
= 26°C/8
= 3.25°C
