Luna makes $500 per 4 hours and Kelly makes $490 per 3 hours Luna works 8 days and Kelly works 10 days

Who makes more money?

Kelly earns more.

Step-by-step explanation:

Find how much Luna makes first.

24hx8days=192 hours

Then put the 192 hours into groups of 4.

192h/4h=48

Now, we take 48 x 500 to find how much Luna makes.

48x$500=$24000

Now, we have found how much Luna makes. Now, we find how much Kelly makes.

24hx10d=240h

Then put the 240 hours in groups of three.

240h/3h=80

Now, we take 80x$490

80x$490=$32900

step-by-step explanation:

(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
