Question

Choose the correct expression for: 10 decreased by 3x O A. 10+ 3x B. 10 – 3x O C. 3x (10) OD 10 OE 3x - 10​

Answer 1

10 - 3x

Explanation:

Note the term, "decreased BY". This means that we have to remove 3x from 10.

If it says, "decreased TO", it means that from 10, there are only 3x remaining.
