Apply the communitive property to 13x7x21 to rearrange the terms and still get the same solution can you explain how you got the answer

problem:

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

f(5/2) = 10/3

i hope this !

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
