Answer:

12

Step-by-step explanation:

x = 2n

2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 80

10n = 60

n = 6

x = 12

12 + 14 + 16 + 18 + 20 = 80

Help me please i’m really confused on it :) thankyou
Nata [24]

A is 6:55

B is 37 Minutes

C is 15:12

Step-by-step explanation:

so basically its just adding minutes to a clock, like if its 1:00 o clock and 40 minutes pass it will be 1:40 or if its 12:00 and 25 minutes pass it will be 12:55. There's 60 minutes in an hour so if the time is, let's say, 12:45 and 30 minutes go by itd be 1:15.

C is a little more tricky but thats just because its military time.:) basically instead of going to 12 am to 1 pm it would go from 12:00 AM to 13:00 PM

Find the value of x.<br> (x + 30)
taurus [48]

Answer:

x=55

Step-by-step explanation:

The exterior angles of a polygon add to 360.

x+x+x+x+x+x+30 = 360

Combine like terms

6x+30 = 360

Subtract 30 from each side

6x+30-30 = 360-30

6x = 330

Divide by 6

6x/6 =330/6

x =55
