Which ratio is also equal to StartFraction R T Over R X EndFraction and StartFraction R S Over R Y End Fraction?

ST/XY

Step-by-step explanation:

(RT/RX)/(RS/RY)= ST/XY

if the shapes are equal  and the same then the ratio are equal

if RT is corresponds to RX and RS is corresponds to RY then TS corresponds to TS

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
