Question 148023
Is the equation {{{P = 5 + 5/(11d)}}} ?



{{{P=5+5/(11*d)}}} Start with the given expression.



{{{P=5+5/(11*11)}}} Plug in {{{d=11}}} 



{{{P=5+5/121}}} Multiply {{{11}}} and {{{11}}} to get {{{121}}}.  



{{{P=610/121}}} Combine the fractions.



{{{P=5.041}}} Approximate the fraction



So the pressure is about 5.041 PSI

OR....

Is the equation {{{P = 5 + 5/d}}} ?




{{{P=5+5/d}}} Start with the given equation.



{{{P=5+5/11}}} Plug in {{{d=11}}} 



{{{P=55/11+5/11}}} Multiply {{{5}}} by {{{11/11}}}



{{{P=60/11}}} Combine the fractions.



{{{P=5.4545}}} Approximate the fraction.



So the pressure is about 5.4545 PSI
