For them knowing i have dyslexia...they sure like to screw with my head... "I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?" If J represents John's age, then which of the following equations could be used to solve the problem? 3J + 15 = 3J - 1 3(J + 15) = J - 1 J + 15 = 3J - 1 J + 15 = 3(J - 1)

Before I answer your question, just a quick question, what grade math are you in, and how old are you?

OpenStudy (anonymous):

im 15...and coordinate algebra ab

OpenStudy (anonymous):

So grade what?

OpenStudy (anonymous):

9th

OpenStudy (anonymous):

Okay, is this normal grade 9 math?

OpenStudy (anonymous):

Yea...Why does this matter

OpenStudy (anonymous):

Because, I was an old math teacher, and just wanted to catch up on what skill level goes to what grade. I would say this is right on track. :)

OpenStudy (anonymous):

O...k...

OpenStudy (anonymous):

Sally is 8. John is 9. Frank is 24.

OpenStudy (anonymous):

8 times 3 is 24. 9 (John's age) plus 15 is also 24.
