Answer:
<h2><u><em>
n = 4</em></u></h2>
Step-by-step explanation:
3n + 16 = 7n
3n - 7n = -16
-4n = -16
n = -16 : (-4)
n = 4
---------------- check
3 * 4 + 16 = 7 * 4
12 + 16 = 28
28 = 28
the answer is good
120 degrees because supplementary degree is 180 so 60+ 120 equals 180 degrees
The only answer that works is B
Energy and work energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energy.
Sorry for the messy working but this is the answer in the box. Comment if you have any questions. Sorry again for the mess. I basically used algebra to manipulate the equations for AP and GP
