Question

If x = 5, then which inequality is true?

a
-2x ≥ 12

b
x – 2 < 7

c
2x > 12

d
x – 7 > 2

Answer 1

the correct answer is b

Step-by-step explanation:

if x = 5

5 - 2 = 3

but x - 2 < 7

then 3 is less than 7

Answer 2

b

Step-by-step explanation:

x-2<7

add 2 to both sides

x<9

5<9

and that's true because 5 is smaller than 9.
