Which of these is a mathematical expression?

A
B
4 - 3r

C
4 - 3r = 1

D
“Happily ever after”

The mathematical expression is C: 4 - 3r = 1.

are you sure?

Apologies for the confusion. You are correct, C is not a mathematical expression. A mathematical expression typically consists of numbers, variables, and mathematical operations. In this case, the correct answer would be B: 4 - 3r.

thanks
