her avrige went up. her averige was 90. it is now 83

Step-by-step explanation:

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 !

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
