Let the number be x
reciprocal=1/x
2 more the reciprocal=1/2+x
but 1/2+x=3(1/x)
1/2+x=3/x
x=6+3x
x=-2
Answer:
5.18 pounds per square inch
Complete question:
If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.
Step-by-step explanation:
According to the Gay Lussac's Law:
where, P and T are the pressure and temperature of an enclosed ideal gas.
Given:
Initial pressure 
= 6 pounds per square inch
Initial Temperature 
=440° F
Final Temperature 
=380° F
Final Pressure 
=?
Substituting all values in the formula
= 
= 5.18pounds per square inch

Answer:
They caught: 11/12 pounds of fish
Explanation:
First, you need to change them to the same common denominator. Since 3 and 6 already go into 12, you just have to change 1/3 and 1/6 to a denominator with 12.
First, you need to change 1/3 to 4/12. By doing that, you do 1/3x4/4=4/12.
You then have to change 1/6 to 2/12. By doing that, you do 1/6x2/2=2/12.
Then you just add up all the fractions and simplify 4/12+2/12+5/12=11/12.
You can't simplify 11/12 any further so your answer would be:
They caught 11/12 pounds of fish in total.
