Answer:

x = -7

Step-by-step explanation:

Given:

5 – x = 12

Subtract 5 from both sides

5 – x - 5 = 12 - 5

- x = 7

Note: the coefficient of -x is -1

- x = 7

Divide both sides by the coefficient of -x

- x / -1 = 7 / -1

x = -7

Check

5 – x = 12

5 - (-7) = 12

5 + 7 = 12

It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value

What is the kinetic Energy of a camion of 5,000 kg and turn at 100km/h ?
Alex787 [66]

Step-by-step explanation:

Given

mass (m) = 5000 kg

velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s

Now

Kinetic energy

= 1/2 mv²

= 1/2 * 5000 * 27.78²

= 1929321 joule
