Write an arithmetic expression that calculates the average of 18 and 46. you may already know that: the average of two numbers is their sum divided by 2 the symbol for division is /, thus 10 divided by 5 is written as 10/5 division has higher arithmetic precedence than addition parentheses 's) may be used to override precedence

In this question , we have to write an arithmetic expression that calculates the average of 18 and 46.

TO find the average, we have to add the numbers and divide by 2.

So here we have to add 18 and 46 and divide by 2, that is

And that's the required algebraic expression .

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
