The starting temperature was 0°C. Then it increased equally 4 times until it was warmer than 20°C. Which inequality expresses the number of degrees d, by which the temperature could have increases each time?

Answer 1

The inequality that expresses the number of degrees d by which the temperature could have increased each time is:
4d > 20 - 0
4d > 20
d > 5

Therefore, the temperature could have increased by more than 5°C each time.
