Missy watches 5 reality shows, each lasting 28 minutes, so the total time spent on reality shows is 5 * 28 = 140 minutes.
She also watches x cartoons, each lasting 10 minutes, so the total time spent on cartoons is x * 10 minutes.
The total time spent watching TV is the sum of the time spent on reality shows and cartoons: 140 + x * 10.
We are given that the total time spent watching TV is 150 minutes, so we can write: 140 + x * 10 = 150.
Solving for x, we get: x = 1.
The value of x is 1.
#### 1
