![8x+10-2x=4(x-5) \\ \\ 6x+10=4x-20 \\ \\ 2x=-30 \\ \\ x=-15](https://tex.z-dn.net/?f=8x%2B10-2x%3D4%28x-5%29%20%5C%5C%20%5C%5C%206x%2B10%3D4x-20%20%5C%5C%20%5C%5C%202x%3D-30%20%5C%5C%20%5C%5C%20x%3D-15)
Step-by-step explanation:
If you mean, 2.4 divided by x equals 5,
and we're to find x,
x=2.4÷5
x=0.48

Answer:
AB = √116 ≈ 10.77
Step-by-step explanation:
Use the formula that calculate the distance between two points:
![L = \sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2}}](https://tex.z-dn.net/?f=L%20%3D%20%5Csqrt%7B%28x_%7B2%7D%20-%20x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D%20-%20y_%7B1%7D%29%5E%7B2%7D%7D)
L means length
For the x and y, substitute a coordinate value that you will label as set 1 or 2.
For example:
A (-3, 7) will be set 1. x₁ = -3 y₁ = 7
B (7 , 3) will be set 2. x₂ = 7 y₂ = 3
Substitute the points into the formula to find the length AB. Simplify.
![L = \sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2}}](https://tex.z-dn.net/?f=L%20%3D%20%5Csqrt%7B%28x_%7B2%7D%20-%20x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D%20-%20y_%7B1%7D%29%5E%7B2%7D%7D)
Solve inside the brackets first
Square each term under the root
Add under the root
Final exact answer is radical (root) form
Final approximate or rounded answer to 2 decimals
The length of AB is the squareroot of 116, or about 10.77 units.
