Ineed with can someone . tell me if i’m right.

You did:

5 episodes / 4 hours = 1.25 episodes/hour

You found how many episodes they watched in one hour, when you should have found how many hours they watched one episode. This is because you need to find how long it took them to watch 24 episodes.

So instead:

4 hours / 5 episodes = 0.8 hours/episode

Then you multiply 0.8 and 24 = 19.2 hours

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
