Question 493928
We only have one unknown "number," so assume the number is x.


1. Twice a number means multiply the number (x) by 2. Usually it is denoted by 2x. Four more than twice a number means add 4 to twice the number (2x) or 4+2x.


Try the other ones the same way. Note that "difference" means subtract, "product" means multiply, and "quotient" means divide.
