Subtract 4 from -17, from 3x+4, and from 19:
-21 < 3x < 15
Divide all terms by 3:
-7 < x < 5 (solution)
Qt=r(s+t)
multiply out
qt=rs+rt
2(1)+3(3)+4=15
2+9+4=15
Or
2(4)+3(1)+4=15
8+3+4=15
So either one would work
3.93 is the correct answer.
I hope this helps.
K = (y °F – 32) ÷ 1.8 + 273.15 or K = (y °F – 32) x 5/9 + 273.15
