The distance a train travels d is proportional to a constant rate of speed r at different times t which equation shows the relationship between the speed of the train and the distance traveled A r=dt B r=d+t C r=d-t D r=d/t

D

Step-by-step explanation:

d = rt so to isolate r you divide both sides by t, leaving you with r=d/t

its basically speed=distance/time, or s=d/t if that's more farmiliar to you

idk

step-by-step explanation:

do it yourself, cause that made me do it myself today, in english!

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
