Answer:

Step-by-step explanation:
1) Simplify 1/3 ( x - 10) to x-10/3.

2) Multiply both sides by 3.

Simplify 4 × 3 to 12.

4) Add 10 to both sides.

5) Simplify -12 + 10 to -2.

So, therefor, the answer is, x = -2.
The correct answer is 140 because the mean, average, number from July per day represents how many people would have visited each day if they were all even.
If there were 20 more people each day in August, the mean would be 140. This would represent how many people visited each day.
Answer:
625 ft^2
Step-by-step explanation:
Given
--- perimeter
Required
The largest area
The perimeter is calculated as:

So, we have:

Divide both sides by 2

Make L the subject

The area is calculated as:

Substitute 

Open bracket

Differentiate with respect to W

Set to 0; to get the maximum value of W

Collect like terms

Divide by -2

So, the maximum area is:
