I am pretty sure x is 9 because if you divide 14 by 2 you get 7. 18 divided by 2 is 9.
Here is the equation:
![18+4 \times 3](https://tex.z-dn.net/?f=18%2B4%20%5Ctimes%203)
You have to use PEMDAS
![\bf Parentheses \\ Exponents \\ Multiplication\\ Division \\ Addition \\ Subtraction](https://tex.z-dn.net/?f=%5Cbf%20Parentheses%20%5C%5C%20Exponents%20%5C%5C%20Multiplication%5C%5C%20Division%20%5C%5C%20Addition%20%5C%5C%20Subtraction)
Since multiplication is before addition, first multiply. You need to multiply 4 by 3.
![4 \times 3 = 12](https://tex.z-dn.net/?f=4%20%5Ctimes%203%20%3D%2012)
Here is your new equation:
![18+12](https://tex.z-dn.net/?f=18%2B12)
All you need to do is add the two numbers. Add:
![18+12=30](https://tex.z-dn.net/?f=18%2B12%3D30)
That means your answer is 30

Answer:
temperature on the 5th days was -3 degree Celsius
Step-by-step explanation:
Mean is the average of the numbers
As per the statement:
The mean temperature for the first 4 days in January was 7°C.
Sum of the first 4 days temperature = ![4 \cdot 7 = 28^{\circ} C](https://tex.z-dn.net/?f=4%20%5Ccdot%207%20%3D%2028%5E%7B%5Ccirc%7D%20C)
It is also given that:
the mean temperature for the first 5 days in January was 5°C.
then;
Sum of the first 5 days temperature = ![5 \cdot 5 = 25^{\circ} C](https://tex.z-dn.net/?f=5%20%5Ccdot%205%20%3D%2025%5E%7B%5Ccirc%7D%20C)
We have to find the temperature on the 5th days.
![\text{Temperature on 5th days}=\text{Sum of first 5 days temperature}-\text{Sum of first 4 days temperature}](https://tex.z-dn.net/?f=%5Ctext%7BTemperature%20on%205th%20days%7D%3D%5Ctext%7BSum%20of%20first%205%20days%20temperature%7D-%5Ctext%7BSum%20of%20first%204%20days%20temperature%7D)
Substitute the given values we have;
![\text{Temperature on 5th days} = 25-28 =- 3^{\circ} C](https://tex.z-dn.net/?f=%5Ctext%7BTemperature%20on%205th%20days%7D%20%3D%2025-28%20%3D-%203%5E%7B%5Ccirc%7D%20C)
Therefore, the temperature on the 5th days was -3 degree Celsius
