3648.24 + 364.824 / ? - 36.4824 = 3794.1696

Correct answer: A. 2

  • A. 2
  • B. 3
  • C. 4
  • D. 5

Explanation

First isolate the unknown term: 3648.24 + 364.824 / ? - 36.4824 = 3794.1696, so 364.824 / ? = 182.412. Since 182.412 x 2 = 364.824, ? = 2, option a. The likely mistake is choosing b, 3, by estimating the division instead of isolating the term.

About Linear Equations

Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
