The temperature was 10°F. It dropped so that the temperature was 0°F. ___°F represents the change in temperature. Is it 10 or -

yan [13]

Answer:

$Change = - 10^{\circ}F$

Step-by-step explanation:

Given

$Initial = 10^{\circ}F$

$New = 0^{\circ}F$

Required

Determine the change in temperature

This is calculated by:

$Change = New - Initial$

Substitute values for New and Initial Temperatures

$Change = 0^{\circ}F - 10^{\circ}F$

$Change = - 10^{\circ}F$

Hence, the change in temperature is: $- 10^{\circ}F$
