The left and right page numbers of an open book are two consecutive integers whose sum is 345.345. find these page numbers.

x is the first number so x+1 is the number just after it.

Adding them up gets to x+(x+1) = 2x+1. Set this equal to 345 and solve for x. See the attached image for the steps. The solution to the equation 2x+1 = 345 is x = 172 which means x+1 = 172+1 = 173.

The two page numbers are 172 and 173. Note how 172+173 = 345

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
