Which formula would calculate the father's age?

Answer 1

more options please... unless your supposed to write it yourself??

Answer 2

and by it i mean the equation

Answer 3

Let s = age of son
F = 3s + 1
s = 20
F = 3(20) + 1

Answer 4

idk

Answer 5

idk

Answer 6

s=20
f-1=3s
f=3*20+1=61

Answer 7

1. F=3(20-1)
2. F + 1 = 3(20)
3. F - 1 = 3(20)

these are the three i have to pick from

Answer 8

Look at the last one: F - 1 = 3(20)
add 1 to both sides: F = 3(20) + 1
That was my solution
