Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
8x + 2 > 34
-2 -2
8x > 32
8x (÷ 8) > 32 (÷ 8)
x > 4
so x can equal any number from 5 and infinity

Answer:
14 minutes
Step-by-step explanation:
4 x every 100 bottles
100, 200, 300 = 3
4 x 3 = 12
if 4 minutes is for every 100 bottles, then 50 is half of 100. so 4 divided by 2 is 2
12 + 2 = 14
