what is the expression for the word problem emma weighs 38 pounds gavin weighs x pounds less

Answer 1

First, assign variables. Let's use "E" for Emma's weight, and "G" for Gavin's weight.

Writing equations, we can then say:

E = 38

G = 38 - x

Note that these are equations, which are more that just expressions. (An expression is some combination of constants and variable used to describe a relationship.....x + 3 is an expression, and x + 3 = 8 is an equation)
