Two more than 16 times a number is the same as 21 less than the product of -7

Step-by-step explanation:

Let the number be 'n'

       16n + 2 = -7n - 21   {add 7n to both sides}

16n + 2 +7 n = -21         { combine like terms}

16n + 7n + 2 = -21

       23n + 2 = - 21     {subtract 2 form both sides}

             23n = -21 - 2

             23n = -23          {Divide both sides by 23}

       23n/23 = -23/23

                 n = -1

i think is g(1)=-1.

hope that i can

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
