I don’t know I really don’t know, I am very confused ahhhhhhh!
Set up a proportion:
4.1/22 = 12.3/x
Cross multiply:
4.1 * x = 22 * 12.3
4.1x = 270.6
Divide 4.1 to both sides:
x = 66
Sorry i cant exactly help you with this one because im in 6th grade so i dont really know problems like this yet.
The answer for f(x)-g(x) is
.The solution can be obtained by use of concept of functions.
<h3>What is a function?</h3>
A function, in mathematics, can be defined as an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).It useful in mathematical representation of scientific quantities.
We can perform addition and subtraction operations on functions.
