Question

Solve the inequality for x. 1/2 x − 2 > 22

A) x > 12
B) x > 48
C) x > −12
D) x > −48

Answer 1

B x > 48

Explanation:

1/2x -2 >22

Mulitply both sides of the inequality by 2

x - 4 > 44

Move the constant to the right

x > 44+4

Add the numbers

x>48

Answer 2

B is correct

1/2x-2>22

Remember 1/2=0.5

We write the equation as

0.5x-2 >22

Collect like terms

0.5x > 22+2

0.5x>24

Divide through by 0.5

X>24/0.5

X>48

Option b
