Ef=19, as given in the question.
Answer:
75
Step-by-step explanation:
By "composite" we mean "numbers that can be factored further."
The numbers between 10 and 20 but not including 10 or 20 are:
12, 14, 15, 16, 18
12, 14, 15, 16 and 18 are all composite numbers (all can be factored).
Their sum is 75.
A.2 I did graph on my calculator finds out the function intersect both x-axis and y-axis(Hope it help:)
You use pemdas and they both equal to 77. So yes they are equivalent.
I think what you are looking for is the equation on how this could be displayed.
The baseline is 4, and the hourly rate of r.
This can be shown by:
4 + r = cost
