The sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The statement that is given to us is" the sum of forty-five and a number", therefore, the expression that will represent this can be written as,
45 + n,
Now, if the value of n is 1.1. Then the sum will be,

Hence, the sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1

Hello from MrBillDoesMath!
Answer:
The solution set is the set all all real number m
Discussion:
3(2m-1) <= 6m-2 =>
3*2m - 3*1 <= 6m-2 =>
6m - 3 <.= 6m-2 => (Subtract 6m from both sides)
0-3 <= -2 =>
-3 < = -2
As -3 <=-2 is always true the solution set is the set all all real number m
