Answer:
x = 15
The median is the middle number, however, in this case there are two:
25 and x
The formula is:
23 + x/2 = 30.5
Subtract 23 from both sides:
23 + x - 23 = 30.5 - 23
Simplify:
x/2 = 7.5
Multiply both sides by 2:
2x/2 = 7.5 ⋅ 2
Therefore:
x = 15
Answer:
-2x^{2}-12x-26
Step-by-step explanation:
(x+3)^2 = x^2+6x+9
-2(x^2+6x+9)-8
-2x^2-12x-18-8
-2x^2-12x-26
Answer:
81 lots of 5,000 square feet fits in the property.
Step-by-step explanation:
<em><u>The first step </u></em>is calculate the square feet of the minimum area:

<em><u>Second,</u></em> from the ten acres we subtract the 26,000 feets of roads:

<em><u>Third,</u></em> we divide the lot area over the available square feet

81 lots of 5,000 square feet fits in the property.

Step-by-step explanation:
Given: The low temperature on Monday was 16°F. The low temperature on Tuesday was 18°F cooler. The low temperature on Wednesday was –4 times Tuesday’s temperature.
To find: expression that can be used to describe the low temperature on Wednesday
Solution:
Temperature on Monday = 16°F
So,
Temperature on Tuesday = 
Temperature on Wednesday = 
So, expression
can be used to describe the low temperature on Wednesday.
Also,
\,\,\left \{\because (a-b)=\left [ a+(-b) \right ] \right \}](https://tex.z-dn.net/?f=%2816-18%29%28-4%29%3D%5B16%20%2B%20%28-18%29%5D%28-4%29%5C%2C%5C%2C%5Cleft%20%5C%7B%5Cbecause%20%20%28a-b%29%3D%5Cleft%20%5B%20a%2B%28-b%29%20%5Cright%20%5D%20%5Cright%20%5C%7D)
So, expression
also represent temperature on Wednesday.
