There cannot be an answer since there is no equation or inequality. The expression can be simplified to -6f -6 or -6(f + 1)
Set it up and follow the steps: 6f - 15 = 3 (then add 15 to each side to isolate the f's from the known numbers) 6f = 18 (then divide both sides by 6 to solve for f) f = 3 prove by substituting 3 for f: 6(3) - 15 = 3 18 - 15 = 3 3 = 3
It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit.15 C is 59 F.
Let f = 1.16666...then 10*f = 16.66666... Subtracting the first from the second, gives 9*f = 10.5 Therefore f = 10.5/9 = 105/90 = 7/6
Approximately -21.1 degrees celsius (or exactly -21 1/9 degrees Celsius) To convert Fahrenheit to Celsius, subtract 32 then multiply by 5/9 (i.e., C=5/9*(F-32)). Plugging in (-6) for F, we get: C=5/9*(F-32)=C=5/9*((-6)-32)=C=5/9*(-38)=-21 1/9=-21.1111...
