What is the solution to -4|-2X +6|=-24

x=0 or x=6

Step-by-step explanation:

Step 1: Divide both sides by -4.

−4(|−2x+6|)

−4

=

−24

−4

|−2x+6|=6

Step 2: Solve Absolute Value.

|−2x+6|=6

We know either−2x+6=6or−2x+6=−6

−2x+6=6(Possibility 1)

−2x+6−6=6−6(Subtract 6 from both sides)

−2x=0

−2x

−2

=

0

−2

(Divide both sides by -2)

x=0.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
