Determine whether the given value is a solution of the equation.

8w = 99; w = 12

The given value is NOT the solution of the equation.

Step-by-step explanation:

For the problem, we know that w = 12 and that when a variable is next to a number that means that multiplication should be used.  So, we will multiply 8 x 12 because w = 12 and we get 96.  This equation states that for this to be true 8w should equal 99.  So since 8w = 96 and not 99 we know this is incorrect.  

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
