What is the answer to the math problem 17-12=8+?

17 -12 = 8 + x

(x= to the unknown number)

17 - 12 = 8 + x = 5

8 + x = 5

8 - 8 + x = 5 - 8

x = 5 - 8

x = -3

Hope this helps!

Step-by-step explanation:

17 - 12 = 8 + x

5 = 8 + x

5 - 8 = x

-3 = x

17 - 12 = 8 + (-3)

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:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
