Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
In this experiment, the scientist cools the gases. This means that she decreases the temperature of the gases.
Based on this, the changes in the temperature will be negative for this experiment to indicate that the gases are losing energy (heat energy).
4 + 3/5 = 23/5 and
2 + 1/3 = 7/3 get a common denominator = 15 ....so....
23/5 = 69/15 and
7/3 = 35/15
So
69/15 - 35/15 =
34/15
Answer:
0.09 OR 9% is her tax
