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.

Answer:
27. (2x + 3)(x + 5)
Step-by-step explanation:
27.
Use the 'ac' method
a*c = 2 * 15 = 30
We need 2 numbers whose product is 30 and whose sum is 13.
3 and 10 look good so we write
2x^2 + 10x + 3x + 15
= 2x(x + 5) + 3(x + 5)
= (2x + 3)(x + 5) answer
The answer is negative 4.
