2. The sum of the reciprocals of two consecutive positive integers is 17/72. Write an equation that can be used to find the two
Lena [83]
To answer this item, we let x be the first positive integer. Then, the second would be x+1. Their reciprocals would be 1/x and 1/(x+1). Then, the equation that would best represent the scenario above is,
                            1/x + 1/(x+1) = 17/72
Solving the equation above,
                           ((x+1) + x) / (x)(x+1) = 17/72
If we take the numerators of both sides of the equation,
                              (x+1) + x = 17
The value of x from the equation is 8 and x+1 would be 9. Thus, the answer would be 8 and 9.

This is easy bro,

So first, all you have to do is finding the half circumstance,

the formula for circumstance is:

C=π*d

since the diameter is 8, therefore,

C=π*8

C=8π,

using 3.14 for π,

8*3.14=

25.12

Hope this helps!!!!
