"20 more than 20" means that you are adding 20 by 20. Then: 20 + 20 = 40 So 40 is 20 more than 20 because 40 - 20 = 20!
Yes. Two equations are necessary to solve this: C = (5/9)(F-32) F - 20 = C Solving yields F = 5 degrees and C = -15 degrees, which are equivalent temperatures. Just to be clear - the value of the temperature given in °F is 5 and value of the equivalent given in °C is -15. 5 is greater than -15 by 20. It's not really correct to say that it is greater by 20° because you can't say what KIND of degrees. A change of 20 °C is equivalent to a change of 45 °F. °C and °F are no more the same units than feet and kilometers are the same units.
Ordinay conversion of 'F' to 'C':C = 5/9 (F - 32)But you said that the 'C' number is 20 more than the 'F' number, soF + 20 = 5/9 (F - 32)Multiply each side by 9/5:9/5 (F + 20) = F - 32(9/5)F + 36 = F - 32Subtract F from each side:(4/5)F + 36 = -32Subtract 36 from each side:(4/5)F = -68Multiply each side by (5/4) = 1.25F = (1.25) x (-68)= -85.The temperature is -85F or -65C. (They're the same temperature.)==================================Check:C = 5/9 (F - 32)C = 5/9 (-85 - 32) = 5/9 (-117) = -65-65 - 20 = -85yay !

20°C is hotter than 20°F. 20°C is equivalent to 68°F.
No F = 9/5 C + 32 = 1.8(20) + 32 = 68F which is warmer than 40F

The H-F bond is more polar than the H-I bond because F (fluorine) is more electronegative than I (iodine). It thus attracts the shared electrons more than does the I, making it a more polar bond.
20 more than -50 = -30

150% more than 20= 20 + (150%* 20)= 20 + (1.5 * 20)= 20 + 30= 50
More than 20 means any number over and above 20.
20 km are more than 20 m meters because kilometers are bigger than meters so 20 meters are less than 20 kilometers.
