Answer:
Jo's age = x = 8 years
Step-by-step explanation:
Let
Jo's age = x
Jo's mother, Anne's age = 4x
In four years time, Anne will be three times as old as Jo.
Jo's age =3( x + 4)
Jo's mother, Anne's age = 4x + 4
How old is Jo?
Equate Jo's age and his mother's age
3(x + 4) = 4x + 4
3x + 12 = 4x + 4
3x - 4x = 4 - 12
-x = - 8
Divide both sides by -1
x = 8
Therefore,
Jo's age = x = 8 years
7.5 i think not 100% sure tho
Answer:
I think 2600 passwords are possible
L = W + 55
2L + 2W = 4242
L + W = 2121
(W + 55) + W = 2121
2W + 55 = 2121
W = 1033 inches L = 1088 inches
