In the inequality 1/ 2 x - 6 &gt; 10, x represents Todd's age. Which phrase most accurately describes Todd's age? A) Todd is old
Tom [10]

Answer:

Option A) Todd is older than 32

Step-by-step explanation:

we have

\frac{1}{2}x-6>10

Solve for x

Adds 6 both sides

\frac{1}{2}x>10+6\\\\\frac{1}{2}x>16

Multiply by 2 both sides

x>32

so

Todd's age is greater than 32

therefore

Todd is older than 32
