satela [25.4K]3 years ago
6 0

Step-by-step explanation:

Start filling in from the bottom, left to right

<u>Row 2 from bottom:</u>

  • -2x + 3
  • 3 + (-5) = -2
  • -5 + 7y = 7y - 5
  • 7y + 1

<u>Row 3 from bottom:</u>

  • 2x + (-2x) + 3 = 3
  • -2x + 3 + (-2) = -2x + 1
  • -2 + 7y - 5 = 7y - 7

<u>Row 4 from bottom:</u>

  • 3 + (-2x) + 1 = -2x + 4
  • 7y - 7 - 5 + 15y =  22y - 12

<u>Row 5 from bottom:</u>

  • -2x + 4 -2x - 6 + 7y = -4x + 7y - 2
  • -2x - 6 + 7y + 22y - 12 = -2x + 29y - 18

<u>Top row:</u>

  • -4x + 7y - 2 - 2x + 29y - 18 = -6x + 36y - 20

Calculate the measure of each exterior angle of a 90 sided regular polygon. Explain.
forsale [732]
90 sides give us 90 angles 

sum of all inside angels is  (n-2) * 180 deg. where n is number of angels 

so one inside angle is 
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.

measure of exterior angle is 360 - 176 = 184 deg.

Answer:

1:17

Step-by-step explanation:

Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.
