Answer:
Infinite solutions.
Step-by-step explanation:
Use the elimination method:
15x - 5y = -20
-3x + y = 4 Multiply this equation by 5:
-15x + 5y = 20 Now add this to the first equation:
0 = 0
So the 2 equations are the same and there are infinite solutions.

Answer:
Week 4
Step-by-step explanation:
A week consist of 7 days (MO, TU, WE, TH, FR, SA, SU)
The mean of the sells done by the store is calculated as the following:
(MO+TU+WE+TH+FR+SA+SU ) 1/7
If we calculate the mean of every given week we have this
Week 1: 6.57
Week 2: 8.86
Week 3: 2.28
Week 4: 8
Since a typical day the jewelry store sells 8 bracelets, in a typical week, the mean of bracelets sold is 8.
The week 4 is the best estimate of the jewelry store's weekly sales throughout the year.
