The errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
From the question, we are to determine the errors that Emma made
The given statement is
"The quotient of six and a number, x, is the same as negative two times the difference of x and 4.5"
"The quotient of six and a number, x", can be expressed as
6/x
"Two times the difference of x and 4.5", can be expressed as
2(x - 4.5)
Hence, the errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
