The sum of three consecutive odd numbers is one hundred fifty - nine

x + (x + 2) + (x + 4) = 159

Combine like terms.

3x + 6 = 159

Subtract 6 from both sides.

3x = 153

Divide both sides by 3.

x = 51

51 + 53 + 55 = 159

step-by-step explanation:

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

i hope this you!
