Answer:
Step-by-step explanation:
Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...
k + (k -5) = 21
2k = 26 . . . . . . . add 5, collect terms
k = 13 . . . . . . . . . divide by 2; Kim's age
k -5 = 8 . . . . . . . Jack's age
Kim is 13; Jack is 8.
Answer:
c = 72
a = 51
b = 57
x = 28
Step-by-step explanation:
2x+1 + 2x-5 = 108
4x -4 = 108
4x = 112
x = 28
(2(28)-5)= 51
(2(28)+1) = 57
