On a digital clock, what is the number that represents the number of hours, if it is know that the remaining part of the day is 60% of the part of the day that has passed?

see the explanation

Step-by-step explanation:

Let

x ----> the remaining part of the day

y ----> the part of the day that has passed

we know that

In a day we have 24 hours

----> equation A

----> equation B

Solve the system by substitution

substitute equation B in equation A

solve for y

so

In a digital clock the number that represent the number of hours is 15:00 (Military time)

In military time, the hours are numbered from 00 to 23

To convert to standard time

15;00-12:00=3:00 pm

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

if you was gonna solve for a, a is a   < -12
