3.88 to 219

Step-by-step explanation:  ok so if the data is O+ donors to B+ donors and you have to write the comparison in three different ways then you look on the chart to see that O+ is 97 & B+ is 25 then it would be 97 to 25. 97 t0 25 & 25 to 97 So I’m thinking next you have to divid  97 by 25 to get 3.88 to 219 .

I might be wrong and if I am i’m sorry.

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
