Help solve math.

Step-by-step explanation:

4(w+2)-5(w+1) = -w+3

w-3 4(w+2)-5(w+1)=w-3= -70/39

-w+3=-70/39

w=187/39

hope this helps (sry if im wrong :-/)

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!

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
