SSSSS [86.1K]3 years ago
8 0

Answer:

{x,y} = {3,-2}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x - 8

// Plug this in for variable  y  in equation [2]

  [2]    3x - 2•(2x-8) = 13

  [2]    -x = -3

// Solve equation [2] for the variable  x

  [2]    x = 3

// By now we know this much :

   x = 3

   y = 2x-8

// Use the  x  value to solve for  y

   y = 2(3)-8 = -2

Solution :

{x,y} = {3,-2}

There are 60 office suites in a downtown building. For how many office suites does company C service the computers? -Company A s
natima [27]
Company C services 16 office suites.

Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5.  Find a common denominator; 15 is the smallest:

1/3=5/15
2/5=6/15

5/15+6/15 = 11/15

This means that 1-11/15 = 4/15 of the suites are serviced by Company C.

4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16
