if the temperature starts at 0°f and drops 2 degrees an hour, how many hours would it take it to reach -8 °f? write a number sentence and solve.
Can you please help me Mrs. Sue
If I gave you $2 each hour, how long would it take for you to have $8?
Same problem, but using positive numbers.
4 hours am I right
Do I divide
correct
Thanks
To determine how many hours it would take for the temperature to reach -8 °F, we can set up a number sentence based on the given information.
Number sentence: 0°F - 2°F/hour × h = -8°F
Here, "h" represents the number of hours it would take for the temperature to reach -8°F.
Now, let's solve the equation step by step:
0 - 2h = -8
Add 2h to both sides:
2h = 8
Divide both sides by 2:
h = 4
Therefore, it would take 4 hours for the temperature to drop from 0°F to -8°F.
So, the answer is: It would take 4 hours to reach -8°F.
