if u write seven more than a number in an algebraic expression would it be in+7
I guess, if "in" is the number.
Generally, though, single letters are used. So, if
x is a number in an expression, then
x+7 is 7 more than the number.
Yes, that's correct. If you want to write "seven more than a number" as an algebraic expression, you can represent the number as 'n' and write it as 'n + 7'.
No, writing "seven more than a number" in an algebraic expression would be represented as "x + 7", assuming "x" represents the unknown number.
To understand why, let's break it down:
- "A number" is represented by the variable "x" (or any other letter).
- "Seven more than a number" means adding 7 to that unknown number.
- Since we don't know the exact value of the number, we use the variable "x".
- Adding 7 to "x" is written as "x + 7".
So, an algebraic expression for "seven more than a number" would be "x + 7".
