I am having trouble figuring out the final step when i get to multiply 5/9(1955.6) to get the set solution. Can you help. the question is below
a metal stays solid at fahrenheit temperature below 1987.6. determine (in terms of an inequality) those celsius temperature for which the metal stays solid. use the formula f=9/5c+32

F= 9/5 C + 32
T<1987.6F
then
1987.6> 9/5 C+32
5*1955>9C
C<1955*5/9
C<I don't know what your problem is here. multiply 1955*5, then divide by 9
the temp C to stay solid will be below that.
