Which one of the following equations is equivalent to 3x-12 = -9? A 3 - 5 = -6
B 70 - 3=4
2x = 4
D 2+3 = 2 - 1

the answer choices don't make sense but I can help u with solving the equation it's x = 1

now that u know this go through your answer choices and solve their equation and see which one produces x = 1 and that'll be the answer!!

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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
