Answer:

x+11-14

Step-by-step explanation:

The temperature rose by 11 and fell by 14 so you add 11 and subtract 14 from the original number.

Answer:

T + 11 - 14 = T - 3

Step-by-step explanation:

Let's call T to the initial temperature.

Between the time iko woke up and lunchtime, the temperature rose by 11. So, the temperature at that time was: T + 11

Then by the time he went to bed, the temperature dropped by 14. So, we have to subtract 14 to the previous temperature, that is, T + 11 - 14 = T - 3

In the picture attached, the model using integer chips is shown. The zero pairs are shown in rectangles.
