61. Often it is necessary to rearrange an equation so that one variable is expressed in terms of others. For example, the equation D = 3t expresses D in terms of t. To express t in terms of D, divide both sides of this equation by 3 to obtain D/3 = t. (a) Solve the equation C = 2πr for r in terms of C.
(b) Solve the equation p = 2w + 2h for w in terms of p and h.
(c) Solve the equation 3x − 2y = 6 for y in terms of x.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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
