X + 2(x + 1)= 46
x + 2x + 2 = 46
3x + 2 = 46
3x = 44
x = 14 2/3

14 2/3, 15 2/3

Tell whether the ordered pair is a solution of the system of equations.
katovenus [111]

Answer:

2x + y = 5

y = 4x – 1

Substitute (2, 1) into system, then:

2x + y = 5  => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)

y = 4x– 1   => 4 x 2 - 1 = 1  => -7 = 1 (not satisfied)

=> Option 3 is correct.

Hope this helps!

LekaFEV [45]

Answer:

There were 300 videos.

Step-by-step explanation:

Since there are 24 videos that got awards, and that's only 8% of the total videos, you put those together. We want the number of 100% of the videos. I would solve this by setting up a ratio and solving for x. This is would look like:

\frac{24}{8} =\frac{x}{100}  

In order to get to 100, you must multiply 8 by 12.5. Therefore, you can multiply 24 by 12.5 to complete the ratio. That would make the ratio look like:

\frac{24}{8} =\frac{300}{100}

Therefore there are 100% of the videos in the contest is 300.
