Four times a number munis 5 times another number is equal to 21. Three times the sum of the two numbers is 36. What are two numb
Ronch [10]

Let the first number be represented by "x".

Let the second number be represented by "y".

"Four times a number..." = 4x

"... minus 5..." = 4x - 5

"... times another number..." = y(4x - 5)

"... is equal to 21." = y(4x - 5) = 21

y(4x - 5) = 21

"Three times the sum of the two numbers (x & y) is 36." = 3(x +y) = 36

3(x + y) = 36

y(4x - 5) = 21

1) solve for "y"

   1) y(4x - 5) = 21

  2) 4xy - 5y = 21

  3) 4xy/4x - 5y = 21/4x

(what you do to one side of the equals sign, you must do to the other so 4x cancels out on the left side, and on the right side you have to divide 21 by 4x)

  4) y - 5y/-5 =  5.25x/-5

  5) y + y = -1.05x

  6) 2y = -1.05x

  7) 2y/2 = -1.05x/2

  8) y = -.525x

2) substitute "y" in for the second equation

   1) 3(x + (-.525x)) = 36

(notice how you now only have x's in this equation)

3) solve for x

   1) 3x - 1.575x = 36

  2) 1.425x = 36

  3) 1.425x/1.425 = 36/1.425

  4) x = 25.3

4) finish finding "y" in either one of the equations using the answer you got for "x"

  1) y(4(25.3) - 5) = 21

 2) y(101.2 - 5) = 21

 3) y(96.2) = 21

 4) 96.2y = 21

 5) 96.2y/96.2 = 21/96.2

 6) y = .22

5) check your work by substituting the two answers back into one of the equations

  1) .22(4(25.3) - 5) = 21

 2) .22(101.2 - 5) = 21

 3) .22(96.2) = 21

 4) 21.164 = 21

A manufacturer makes two type if products X and z at each if two different locations A and B. the materials used to make each if
Snezhnost [94]

Using matrix algebra, the material cost of making one of each product at each location is as follows:​

<h3 />

                       Product X    Product Z

Location A        birr 38          birr 50

Location B        birr 38          birr 49.5

<h3>What is matrix algebra?</h3>

Matrix algebra involves the arrangement of numbers in a rectangular array.

Matrices are arranged in columns and rows to express some mathematical values.

<h3>Data and Calculations:</h3><h3>Matrix O: Materials Requirement Per Unit</h3>

                      Steel    Glass    Plastic

Product X         3            1             2

Product Z         4          0.5           3

<h3>Matrix P: Materials Cost Per Unit</h3>

                      Steel    Glass    Plastic

Location A      10           2           3

Location B       9           3           4

<h3>Matrix R: (O x P) Material Cost of Product X</h3>

                      Steel    Glass    Plastic   Total

Location A     30           2           6          38

Location B     27           3           8          38

<h3>Matrix R: (O x P) Material Cost of Product Z</h3>

                      Steel    Glass    Plastic   Total

Location A     40          1             9          50

Location B     36          1.5         12         49.5

Thus, Product X costs birr 38 at locations A and B, respectively, while Product Z costs birr 50 and birr 49.5 at locations A and B, respectively.
