3 0

Answer:

15 and 18

Step-by-step explanation:

Create a system of equations. Let x and y represent the numbers:

y = x + 3

x + y = 33

Solve by substitution, by plugging in the first equation into the second equation as y:

x + y = 33

x + (x + 3) = 33

2x + 3 = 33

2x = 30

x = 15

Find the other number by plugging in 15 as x into the first equation:

y = x + 3

y = 15 + 3

y = 18

So, the numbers are 15 and 18

GE produces 5 different sizes of TVs using 2 machines. Different sizes of TVs take different amount of time to get processed at

OLga [1]

Answer:

Option # C: 5

Step-by-step explanation:

Decision variables, as the name imply are entities that can have different values in the given scenario and which in turn produce different outcomes. For our question, the variables are the sizes of TVs available, as the production time and profit depend on the sizes. Hence, TV sizes (i.e. 5) are our decision variables.

Furthermore, it does not matter on which machine the TVs are being manufactured as they will take identical time for same TV size. Thus we do not consider the number of machines as our decision variables.
