Answer:
2x -43
Step-by-step explanation:
Distribute 2 to into the parenthesis: 2 * x and 2 * -6
2x + -12 - 31
Combine like-terms: -12 + - 31 = -43
2x -43
IF you need the equation completely simplified, I bEliVe you would be able to divide by 2 to get it: x - 21.5
Answer:
x = 6
Step-by-step explanation:
AC = 5x - 24
AO = 3
AC and BD bisect each other at point O. This means AC ≅ CO.
So, 2(AO) = AC.
2(3) = 5x - 24
Multiply.
6 = 5x - 24
Combine the constants.
30 = 5x
Divide by 5.
x = 6
The distance between two points is the number of units between them
The expression that represents the distance between the points is x - 4
<h3>How to determine the expression</h3>
The points are given as: (4,8) and (x,8)
The distance (d) between points is calculated using:
![d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_2%20-x_1%29%5E2%20%2B%20%28y_2%20-y_1%29%5E2%7D)
So, we have:
![d = \sqrt{(x - 4)^2 + (8 -8)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x%20-%204%29%5E2%20%2B%20%288%20-8%29%5E2%7D)
Evaluate the difference
![d = \sqrt{(x - 4)^2 + 0^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x%20-%204%29%5E2%20%2B%200%5E2%7D)
Evaluate the exponent
![d = \sqrt{(x - 4)^2 + 0}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x%20-%204%29%5E2%20%2B%200%7D)
Evaluate the sum
![d = \sqrt{(x - 4)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x%20-%204%29%5E2%7D)
Evaluate the exponent
![d = x - 4](https://tex.z-dn.net/?f=d%20%3D%20x%20-%204)
Hence, the expression that represents the distance between the points is x - 4

112 of 312 miles @ 30 mph
(312 - 112) of 312 miles @ 60 mph
mathematically represented by the following equation . . .
(112/312)(30) + (200/312)(60)
average speed = 49.23 mph
