Answer:
30,100 - 2150m = 0 m = 14
Step-by-step explanation:
First, the linear equation to find how long it will take would be 30,100 - 2150m , with m being the number of minutes it took. m = 14, because 2150 × 14 equals 30,100, and 30,100 - 30,100 equals 0.
At least about 20 points it can depend on the class but not really.
17
| -18 + 1|
-18 + 1 = -17
So,
| -17| = 17
This is because if | -a|, then | -a| = a
