Where dose this number go on the number line?

2 x pi = about 6.3

I think it goes at 6.3

If you can't do that-- I'd round down to 6

hope that helps

between the 6 and 7 , multiply 2 times 3.14 because pi=3.14

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!
