write an algebraic expression representing three less than half a number
If x is the number you start with, three less than half of that is
x/2 -3
let n = number
half the number, so n/2
three less than, so - 3
putting them together, three less than half a number is:
n/2 - 3

To write an algebraic expression representing three less than half a number, we can follow these steps:
Step 1: Let's assign a variable to represent the unknown number. We'll use "x" for this example.
Step 2: We know that half of a number can be expressed as (1/2)x.
Step 3: To represent "three less than" half of a number, we subtract 3 from (1/2)x.
Putting it all together, the algebraic expression for three less than half a number is:
(1/2)x - 3
