Answer:
2.3
Step-by-step explanation:
on the left side u add 4k+3k=7k
on the right side u subtract 2k-6k=4k
then on the left side u add 2 to each side and u get rid of the 2 on the left side
on the right side u add 5+2=7
then on the right side u add 4k on each side and get rid of the 4k on the right
on the left u subtract 7k-4k=3k
on both sides divide by 3
24 is the simplified answer
The temperature of the air mass would be 5°C after it rises.
Air temperature drops 1°C for every 100 m it rises:
1/100 = x/500
Cross multiply:
500*1 = 100*x
500=100x
Divide both sides by 100:
500/100 = 100x/100
5 = x
The temperature will drop 5°; 10-5 = 5°C for the new temperature.
