Answer:
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Answer:
The required value of x = 28
The required value of y = 32
Step-by-step explanation:
The given two equations are :
Now, we need to solve both the equations and find out the required values of both the unknowns x and y.
Solving equation (1) to obtain value of x. We have,
Solving equation (2) to obtain value of y. We have,
Hence, The required value of x = 28
And The value of y = 32
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.
