Answer:
Let x is number of students falled.
Then 6x is number of students passed. So, 6x + x = 273; 7x = 273, x = 39
Answer: 39 students falled, 273 - 39 = 234 students passed
Step-by-step explanation:
In this particular question, one much understand that all angles in a triangle add up to be 180 degrees. In the 2 angles currently displayed, we have a total of 107 degrees. Subtract that from 180 and we will get 73 degrees for the unknown angle.

Answer:
-(14 - 7x); 7(x - 2); 3x - 14 + 4x
Step-by-step explanation:
for -(14 - 7x) when the negative is distributed you get -14 + 7x which is still 7x - 14
for 7(x - 2) when multiplied in you get 7x - 14
for 3x - 14 + 4x when added together you get 7x - 14
