Twice a number is 27 more than half the number. what is the number?

twice a number: 2x

is 27 more than half the number: 1/2x

2x = 1/2x + 27

Isolate the x. Subtract 1/2x from both sides

2x (-1/2x) = 1/2x (-1/2x) + 27

2x - 1/2x = 27

1.5x = 27

Isolate the x. Divide 1.5 from both sides

1.5x/1.5 = 27/1.5

x = 27/1.5

x = 18

18 is the number

hope this helps

answer: t=3

step-by-step explanation:

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
