HELP PLEASE Ben is 9 years younger than his brother Jeff. in 10 years, the sum of their ages will be 67 how old are they now

Let Jeff's age = x and Ben's age = x - 9.

(x + 10) + (x -9 + 10) = 67

x + 10 + x + 1 = 67

2x + 11 = 67

2x = 56

x = 28

x - 9 = 28 - 9 = 19

Jeff is 28 years old, and Ben is 19 years old.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

i believe that the answer is

b. y-1=-2(x-4)

hope this !
