Question 968461

The Fahrenheit temperature of Phoenix has never exceeded 122 degrees. How would you describe this using Celsius temperature?

Formula: {{{F = (9/5) C + 32}}}

given: {{{F <=122}}}

{{{ (9/5) C + 32<=122 }}}.........solve for {{{C}}}

{{{ (9/5) C<= 122-32 }}}

{{{ (9/5) C <=90 }}}

{{{ C  <=90/(9/5) }}}

{{{ C<= (90*5)/9  }}}

{{{ C <= (cross(90)10*5)/cross(9) }}}

{{{ C<=10*5   }}}

{{{ C<= 50  }}}

The Celsius temperature of Phoenix has never exceeded {{{50  }}} degrees.
