Answer:38
Step-by-step explanation:
if there were 253 children and 6 buses and f 25 children had to go by car then,
253-25=228
228/6=38
Assuming the problems is |-5.75|, the absolute value is simply 5.75
absolute value measures how far away a value is from 0 on a number line. |1| and |-1| both have an absolute value of 1, because if you graphed them on a number line you'd see that they're both 1 unit away from 0. although -5.75 would be on the left, or negative side, of the 0 on a number line, it is still exactly 5.75 units away, and that's what absolute value measures.
