One half the sum of two numbers equals their difference. What are the numbers if their sum is 56

28

Step-by-step explanation:

(1/2)56 = a - b

28 = a - b

a + 28 = 56

a = 28

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
