An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.
2n/5 or (2/5)*n
(x - 25)*4
To write a variable expression for "W increased by 4," you simply take the variable ( W ) and add 4 to it. The expression would be written as ( W + 4 ). This indicates that you are taking the value of ( W ) and increasing it by 4 units.
