I need some help. If you can.

Step-by-step explanation:

3 3/8 = 3 + 3/8 = 24/8 + 3/8 = 27/8

then:

-5/9 + 3 3/8 = -5/9 + 27/8

= -40/72 + 243/72

= 203/72

203/72 = 144/72 + 59/72 = 2 + 59/72

= 2 59/72

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!
