Question

Between the time iko woke up and lunchtime, the temperature rose by 11 degrees. Then by the time he went to bed the temperature dropped 14 degrees. Write an addition expression relative to when iko woke up

Answer 1

X + 11 - 14

Explanation:

Let's asume the temperature when iko woke up: x

Between the time iko woke up and lunchtime, the temperature rose by

11. This means that the temperature at the lunch time is: x + 11

Then by the time he went to bed, the temperature dropped by 14. This means that the temperature at that time was the previous one less 14:

X + 11 - 14

To compare this temperature to the initial temperature T, we have to

subtract it: x + 11 - 14 - x = 11 - 14 = -3. This means that the

temperature at the end of the day was 3 degrees less than at the

beginning
