Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • To solve for 'x', we would have to use inverse operations.
  • We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
  • We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

If the variance of the water temperature in a lake is 30°, how many days should the researcher select to measure the temperature
Jet001 [13]

Answer: The number of days would be 7 days.

Step-by-step explanation:

Since we have given that

Variance = 30°

Standard deviation = √30 =  5.47

Mean = 4°

At 95% confidence, z = 1.96

So, number of days that the researcher select to measure the temperature would be

n=(\dfrac{z\times \sigma}{error})^2\\\\n=(\dfrac{1.96\times 5.42}{4})^2\\\\n=7.053\\\\n=7

Hence, the number of days would be 7 days.

Answer:

x ≤ 10

Step-by-step explanation:

The sign that I used means less than or equal to. So that means that there can either be 10 people exactly, or less than 10 people.
