Answer: the answer is A
Step-by-step explanation:
Answer:
A = 15 B = 25 in four years 19+29 = 48
Step-by-step explanation:
age A and B ratio is 3 to 5
A+4 + B+4 = 48
A + B = 40
A/B = 3/5 A = 3B/5
A + B = 40
3B/5 + B = 40
3B + 5B = 200 multiple both sides by 5
8B = 200
B = 25
A = 3B/5
A = 3(25)/5
A = 15
