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

Answer:
60π
Step-by-step explanation:
Hullo :D
I think this will be a piece of helpful info:
<em>The formula for finding the area of a circle if πd.</em>
<em />
In that case, we just substitute 60 (our d)
So the area will be 60π
If you want that multiplied, you'll get 188.4 (multiplying by 3.14)
Thus, the answer is
.
Answer: B
Step-by-step explanation: I took the quiz and got it right
Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions
5-4*9= 9
just use the properties
A equals 54
im thinking b equals 12 but i could be wrong
a is right though
