Question

Between the time lko woke up and lunchtime,the temperature rose by 11 degrees then by the time he went to bed the temperature dropped by 14 degrees

Answer 1

Missing details:

Write an addition expression for the temperature relative to when Iko woke up.

Answer:

$T = x -3$

Step-by-step explanation:

Let the temperature when he woke up be x

When he woke up, it rises to 11 degrees.

This is represented as:

$t_1 = 11$

At bedtime, it dropped by 14 degrees.

This gives

$\triangle t = 11 - 14$

$\triangle t = -3$

The relative change T is:

$T =Initial\ Temp + Change$

$T = x + \triangle t$

$T = x -3$
