The weather report says that if the temperature drops 10°, it will reach 25° below zero. The current temperature T can be found
by solving the equation T – 10 = –25. Which answer describes the correct method for solving the equation?
1 answer:
Answer:
The current temperature is -15° (15° below zero)
Explanation:
The temperature drops 10°:
T-10°
It will reach 25° below zero:
T - 10° = -25°
We add 10° in both members of the equation:
T - 10° +10° = -25° +10°
The equation is simplified as follows:
T = -25° +10°
T = -15°
The integer -15° can be expressed as 15° below zero.
