Which number line shows the solution to the inequality -2(3x-1)<8
Zigmanuir [339]

Answer:

x  > -1

Step-by-step explanation:

Given

-2(3x - 1) < 8

Required

Show on a number line

-2(3x - 1) < 8

Divide through by -2

\frac{-2(3x - 1)}{-2} < \frac{8}{-2}

3x - 1 > -4

Add 1 to both sides

3x -1 + 1 > -4 + 1

3x > -3

Divide through by 3

x  > -1

1.2million users of social media via mobile devices were added each day. How many users added on an average each second
Pachacha [2.7K]

Answer: 14 new users are added per second

Step-by-step explanation:

1,200,000/24 = 50000

50000/60 = 833.333333333

833.333333333/60 = 13.8888888889

then round because it said on average

so if we round 13.8888888889 we get 14

so on average 14 new users are added per second.

The number of pieces of 1/3 foot tall to make a 6 feet skyscraper is 18 pieces.

The model of a skyscraper comes in pieces and each piece is 1/3 feet tall.

After all the pieces are put together the skyscraper is 6 feet tall.

We have to calculate how many pieces were put together to make the 6 feet skyscraper.

Let X be the number of pieces put together to make a 6 feet skyscraper.

Now,

Each piece = 1/3 feet tall.

Since all the pieces together make 6 feet tall, we can write the number of pieces needed to make 6 feet tall as:

X x (1/3) = 6

X = 6 x 3 = 18

Thus, we need 18 pieces of 1/3 foot tall to make a 6 feet skyscraper.
