After cutting a piece 1.65 m long from a piece of cable, the remaining piece is 3.50 m long. How long was the cable originally?

5.15 m

Step-by-step explanation:

To find how long the cable was originally, find the sum of the length of the piece that was cut off and the length of the remaining piece:

1.65 + 3.5 = 5.15

The cable was originally 5.15 m long.

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
