What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> °
Gnom [1K]

Answer:

The answer to your question is:  111°

Step-by-step explanation:

The sum of the interior angles of a polygon is (n - 2) 180°

This polygon has 7 sides

Then n = 7

Process

  120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180

  120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)

  789 + x = 900

  x = 900 -789

  x = 111°

In a certain clothing store, 4 shirts and 6 ties cost $70, and 2 shirts and 4 ties cost $42. What is the cost of each tie?
Oksanka [162]

Answer:

  $7

Step-by-step explanation:

Your two equations are ...

  • 4s +6t = 70
  • 2s +4t = 42

Double the second equation and subtract the first:

  2(2s +4t) -(4s +6t) = 2(42) -(70)

  2t = 14 . . . . . simplify

  t = 7 . . . . . . . divide by 2

The cost of each tie is $7.
