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

48 develop a fault out of the total built which is 2400 therefore
48/2400
If needs to be simplified then 1/50
Use m-a-t-h-w-a-y they are awesome. Or m-y-m-a-t-h-l-a-b
I think the answer would be <span>A=0.85
B=(1 - 0.15)d
C=85d
D=0.85d</span>
