Solve the inequality. Graph the solution.
−8≤z+6.4
The solution is
Answer:
B
Step-by-step explanation:
In the answer choice B, the " is the same as" can be used to denote an equal sign, and can therefore be written as an equation because an equation requires an equal sign.
Hope that helped! :)
- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then
![8n+2=2n+20\implies6n=18\implies n=3](https://tex.z-dn.net/?f=8n%2B2%3D2n%2B20%5Cimplies6n%3D18%5Cimplies%20n%3D3)
