Solve the equation
1. 23 = 7x
2. b + 8 = 12.2
you have a rack that can hold 30 cds. you can fit 7 more cds on the rack before the rack is full. which equation models this situation appropriately, where x represents the number of cds?
a. x + 30 = 7
b. x - 7 = 30
c. 7 + 30 = x
d. x + 7 = 30

step-by-step explanation:

107 units

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

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
