Step-by-step explanation:

If the baby went to sleep at 9:30 and woke at 2:45.
Then the baby slept 5 hours and 15 minutes.
Just start at 9:30 and skip count 9:30, 10:30, 11:30, 12:30, 1:30, 2:30 that's 5 hours and from 2:30 to 2:45 is 15 minutes.
Hope this helps. :)
Answer:
4 ( 8 - 2 ) = (-3) + 7 -> this is a false statement
Step-by-step explanation:
4 ( 8 - 2 ) = ( -3 ) + 7
Simplify the parenthesis
4 ( 6 ) = (-3) + 7
Multiply;
24 = (-3) + 7
Add, remember, adding a negative number and a positive number is the same as subtracting the negative number from the positive number,
24 = 4
This statement is not true.
