Question

The mathematical expression for an object's weight on Jupiter is 2.54w.
a. Is this a numerical expression or a variable expression?
b. If it is a variable expression, name the variable.
I am so confused...

Answer 1

An expression that has only numbers would be a numerical expression.
If it has letters that represents values, that's variable expression.
In this case w represents your weight on earth (probably, I'm not sure, but it doesn't matter) It's a letter, so this is a variable expression. The letter is the variable.

Thank you so much!!!
