Answer:
5 - 2x
Step-by-step explanation:
Translating words to numbers can be tricky.
Here it says: "5 decreased by twice a number." So you have to imagine-- I started with Five things. Then there was a decrease --twice some variable.
5 take away twice something translates to
5 - 2x
Tricky, because most algebra expressions are written with variables first, then the constants. You could rewrite this expression as
-2x + 5
