First off, because the temperature is decreasing, that means the final answer would be negative, or we can also say that there would be a -1 to be multiplied by the change.
Each hour temperature changes by 7. The question also says that temperature keeps on changing for 3 hours. Therefore the temperature change would be by 3 7's, or 7+7+7.
Lastly, add the -1 from the beginning since it is a negative temperature change, the answer is (-1)(7+7+7)
Multiplication rate is 10¹³/100=10¹¹ per hour.
After 1000 hours there are 10¹¹×1000=10¹⁴
Answer:
if 3x-5=20, then 4x=
3x-5=20
3x= 20+5
3x= 25
x= 25/3
4x=1
if x=25/3
then 4x25/3
80/3
