Question

Which value is a solution to the inequality x – 4 > 15.5? A) x = 21.4 B) x = 17.3 C) x = 15.5 D) x = 19.3

Answer 1

Answer:

A.) x = 21.4

Step-by-step explanation:

When solving the inequality, you can treat the sign like an equal sign. To isolate the "x" variable, you can add "4" to both sides. This eliminates the -4 from the right side.

You are left with the inequality:

x > 19.5

If "x" must be greater than 19.5, the only answer that satisfies this is A.) x = 21.4. All of the other answers are less than 19.5.

Answer 2

$\bf{x -4 > 15.5}$

$\bf{Add \ 4 \ to \ both \ sides.}$

$\bf{x-4+4 > 15.5+4 }$

$\bf{x > 19.5 === > Answer }$
