Answer:

Simplifying

-38 = -0.4k

Solving

-38 = -0.4k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '0.4k' to each side of the equation.

-38 + 0.4k = -0.4k + 0.4k

Combine like terms: -0.4k + 0.4k = 0.0

-38 + 0.4k = 0.0

Add '38' to each side of the equation.

-38 + 38 + 0.4k = 0.0 + 38

Combine like terms: -38 + 38 = 0

0 + 0.4k = 0.0 + 38

0.4k = 0.0 + 38

Combine like terms: 0.0 + 38 = 38

0.4k = 38

Divide each side by '0.4'.

k = 95

Simplifying

k = 95

You play a video game for 15 minutes. You lose 75 points. What integer represents the mean chanpe
jolli1 [7]

Answer:

5

Step-by-step explanation:

I played a video game for 15 minutes and I lose 75 points.

So, at time = 0, point loss =0, and at time = 15 minutes, point loss = 75.

Therefore, the mean change in points per minute is = ( total loss of points / total minutes of playing the game )

= \frac{75}{15} = 5 points per minute.

Hence, the integer 5 represents the mean change in points per minute. (Answer)
