Solve for x. 15 = |3x| A) x = 5 or x = −5 Eliminate B) x = 12 or x = −5 C) x = 5 or x = −12 D) x = 12 or x = −12

x=-5,x=+5

Step-by-step explanation:

The question says 15=|3x|

So to solve this question we will have to eliminate the || from 3x and to do so we will transfer it to 15... when it gets to 15 it will be + or - 15

So let's solve

Starting from +15=3x

Make x the subject of formula

x=+5

Let's move to the -15=3x

Make x the subject of formula

x=-5

Therefore x is either+5 or -5

That's the final answer for the given question...

step-by-step explanation:

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
