Correct question:

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.

Adrian should wake up by 6.14 am

Step-by-step explanation:

Given;

time to walk to school, = 15 mins

time to eat breakfast = 5/12 hour = 25 mins

time to get dressed = 0.7hour = 42 mins

time to shower = 0.15 hour = 9 mins

time Adrian needs to be in school = 7.45 am

Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;

7.45 am - 15 mins = 7.30 am

7.30 am - 25 mins = 7.05 am

7.05 am - 42 mins = 6.23 am

6.23 am - 9 mins = 6.14 am

Therefore, Adrian should wake up by 6.14 am

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
