X + y = 155x - y = 9
Elimination method

(4, ? )

what number is the ?​

Answers

Answer 1
Answer: The ? Is 11.


You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
Answer 2
Answer: 4 + y = 15....1
20 - y = 9.....2

....1*5
20 + 5y = 75....3

....3 - .....2
4y = 60
y = 15

the answer for (?) is 15
i’m not sure if this 100% correct but i’m trying my best to help you

Answers

The independent variable is customers.. No one can tell how many customers are going to come unless they write..

So it can't be or D

The independent variables should be on horizontal line when considered as a scatter plot.

So it's A. The independent variable is customers and is graphed along the horizontal axis

Thank you.

A company has three operational departments namely weaving, processing and packing with capacity to produce three different types of clothes namely suiting’s, shirting’s and woolens yielding a profit of rupees 2 ,4and 3 per meter respectively.1 meter of suiting requires 3 minutes in weaving, 2 minutes in processing and 1 minute in packing. Similarly 1 meter of shirting requires 4 minutes in weaving ,1 minute in processing and 3 minutes in packing.1 meter of woolen requires 3 minutes in each department .In a week total run time of each department is 60,40 and 80 hours for weaving, processing and packing respectively. Formulate this as LPP and find the solution.

Answer: Scroll down for solution

Step-by-step explanation: To formulate this problem as a Linear Programming Problem (LPP), we need to define the decision variables, objective function, and constraints.

1. Decision Variables:

Let's denote the number of meters of suiting, shirting, and woolen produced as:

- x1: Number of meters of suiting produced

- x2: Number of meters of shirting produced

- x3: Number of meters of woolen produced

2. Objective Function:

The objective is to maximize the profit, which can be calculated as follows:

Profit = 2x1 + 4x2 + 3x3

3. Constraints:

a) Weaving Department:

The total run time available for weaving is 60 hours per week. The time required to produce 1 meter of suiting, shirting, and woolen in the weaving department is given as 3 minutes, 4 minutes, and 3 minutes, respectively. Since there are 60 minutes in an hour, the constraint for the weaving department can be expressed as:

3x1 + 4x2 + 3x3 ≤ 60

b) Processing Department:

The total run time available for processing is 40 hours per week. The time required to produce 1 meter of suiting, shirting, and woolen in the processing department is given as 2 minutes, 1 minute, and 3 minutes, respectively. The constraint for the processing department can be expressed as:

2x1 + 1x2 + 3x3 ≤ 40

c) Packing Department:

The total run time available for packing is 80 hours per week. The time required to produce 1 meter of suiting, shirting, and woolen in the packing department is given as 1 minute, 3 minutes, and 3 minutes, respectively. The constraint for the packing department can be expressed as:

1x1 + 3x2 + 3x3 ≤ 80

d) Non-negativity constraint:

The number of meters produced cannot be negative, so we have the constraint:

x1, x2, x3 ≥ 0

Now, we have the LPP formulated with the decision variables, objective function, and constraints. To find the solution, we can use a method such as the Simplex method or graphical method to optimize the objective function while satisfying the constraints.
