Your correct :)

Tabaddress1123:

I couldn't find any thing wrong with it.

Hero:

@theghost22

theghost22:

Translate this sentence into an equation. 53 is the difference of Diane's age and 15 . Use the variable D to represent Diane's age.

Hero:

Yes, the key part of the instruction says "Use $d$ to represent Diane's age". Is that what you did?

theghost22:

Yes

Hero:

Show me where you have used \(d\) to represent Diane's age.

theghost22:

It was telling me the difference which means subtraction

Hero:

I don't see where you have used \(d\) to represent Diane's age.

theghost22:

d -15=

Hero:

Actually, I take that back. The statement you wrote does not reflect the situation given.

theghost22:

Ok so what is the correct one then?

theghost22:

From what i could figure out it would be d-15=53

Hero:

Correct

theghost22:

Do you need me to show my work?

Hero:

No, that's all the work that needs to be done.

Hero:

It did not say "Solve for \(d\)" It only says to translate the given situation into a mathematical statement. Which you have done.

Hero:

@NonportritV2 That's the statement he had originally which was shown to be incorrect.

theghost22:

Yes I just got confused there for a second so that's why I did it wrong

Hero:

But @theghost22 if you do solve for \(d\) what would you get?

theghost22:

Ok so I have one more question that I need to be checked but since I know how to do it I am confident in my answer but I want to be sure.

theghost22:

Well when yous solve for D you get 38

Hero:

Are you sure about that? I get something else when I solve for \(d\)
