Answer:
n =7 or n = -17/3
Step-by-step explanation:
10 - |3n - 2| = -9 (subtract 10 from both sides)
- |3n - 2| = -9 - 10
- |3n - 2| = -19 (multiply both sides by -1)
|3n - 2| = 19
(3n - 2) = 19 or (3n - 2) = -19
For (3n - 2) = 19,
3n - 2 = 19
3n = 21
n =7 (answer)
For (3n - 2) = -19,
3n - 2 = -19
3n = -17
n = -17/3 (answer)
Answer:
3 times
Step-by-step explanation:
She has 1 1/2 hour to spend in the gym.
1 hr = 60 minute
1/2 of an hour
= 1/2 * 60
= 30 minutes.
In total, she spends 90 minutes in the gym.
If 1/3 of an hour is meant in running, it translates into;
1/3 * 60 = 20 minutes
If 1/6 of an hour is spent in weight-lifting, it translates into;
1/6 * 60 = 10 minutes
In total, she spends,
20 minutes + 10 minutes = 30 minutes for both activities.
To obtain the number of times she would perform both activities, we divide the total amount of time spent in the gym by the amount of time spent for both activities.
= 90 minutes/30 minutes
= 3 times for each cycle.
