Can some one tell me what the answer is.

B

Step-by-step explanation:

We know that all of the ages are 7 apart so we don't need to mess with that.

Since Ed's age is 3/2 times Ted's age, we can make an equation.

Ted = t

Ed = e

e = 3/2t

Now we can just substitute and see if it checks out.

21 = 1.5 * 14

And since they are equal B is the answer.

here's a poem i finished a while ago. i hope you like it and that it inspires you.

thus, the first answer choice, y = sec x, is the correct one
