<span>I'm gonna do the example of this equation 2+2, as we all know when we add it together the sum of it is 4 , here are the examples:                                          2 + 2 = 4 is true 
2 + 3 = 4 is false 
x + 3 = 4 is open</span>

sukhopar [10]

The system of equations that can be used to determine the number of small tables and the number of large tables the designer will make is:

y -x = 8

$12y - $6x = $236

<h3>Defining the variables </h3>

Let:

x = number of large tables the designer can make.

x = number of small tables the designer can make.

<h3>Simultaneous equations</h3>

Simultaneous equations are sets of equations that must be solved together in order to determine the required variables. Methods of solving simultaneous equations include:

  • Elimination method
  • substitution method
  • Graph method

Answer:

  • 2nd force: 99.91 lb
  • resultant: 213.97 lb

Step-by-step explanation:

In the parallelogram shown, angle B is the supplement of angle DAB:

  ∠B = 180° -77°37' = 102°23'

Angle ACB is the difference of angles 77°37' and 27°8', so is 50°29'.

Now, we know the angles and one side of triangle ABC. We can use the law of sines to solve for the other two sides.

  BC/sin(A) = AB/sin(C)

  AD = BC = AB·sin(A)/sin(C) = (169 lb)sin(27°8')/sin(50°29') ≈ 99.91 lb

 AC = AB·sin(B)/sin(C) = (169 lb)sin(102°23')/sin(50°29') ≈ 213.97 lb
