6x-2(x+1)>0 a. X>2 b. X<2 c. X>1/2 d. X<1/2

  c.  x>1/2

Step-by-step explanation:

Distribute the -2 to eliminate parentheses:

  6x -2x -2 > 0

  4x -2 > 0 . . . . . . combine terms

Now, you can divide by 4:

  x -2/4 > 0

and add 1/2

  x > 1/2 . . . . . matches choice C

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
