Answer:
D
Step-by-step explanation:
Its an abs value so you have to solve twice. Once for d - 3.5 < or equal to 1.5 which equals 5. You also have to solve for d - 3.5 > or equal to -1.5 which equals 2. So on the graph it has to be less than 5 and greater than 2 so you just connect the two and draw the line over the numbers in between the 2 and 5.

Answer:
7 : 7 : 12 am
Step-by-step explanation:
This question pretty much requires us to obtain the lowest number that is common to all three times. The qay to obtain this is by finding the LCM of all three numbers.
This is given as;
48 = 2 × 2 × 2 × 2 × 3
72 = 2 × 2 × 2 × 3 × 3
108 = 2 × 2 × 3 × 3 × 3
The LCM is = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 432 seconds.
Converting to minutes by dividing by 60, the time is = 432 ÷ 60 min = 7 min 12 sec
The next time they would change simultaneously is; 7am + 7 min 12 sec = 7 : 7 : 12 am
