Question 11 • Mathematics I

Which equation can be used to represent "six added to twice the sum of a number and four is equal to one-half of the difference of three and the number”?

Answer
A
6 plus 2 times open paren x plus 4 close paren is equal to 1 half times open paren x minus 3 close paren
B
6 plus 2 times open paren x plus 4 close paren is equal to 1 half times open paren 3 minus x close paren
C
open paren 6 plus 2 close paren times open paren x plus 4 close paren is equal to 1 half times open paren 3 minus x close paren
D
open paren 6 plus 2 close paren times open paren x plus 4 close paren is equal to 1 half times open paren x minus 3 close paren

Explanation

“Twice the sum of a number and four” is 2(x + 4), and adding six gives 6 + 2(x + 4). “The difference of three and the number” means 3 − x, so one-half of that difference is 1/2(3 − x). Therefore, choice C represents the statement.
