|z+7|=12/3
|z+7|=4
z+7=4
-(z+7)=4
solve the first equation:
z+7=4
z=-3
solve the second equation:
-(z+7)=4
z=-11
z=-11,-3
They would meet after 4 hours, as 65 x 4 = 260. And 60 x 4 = 240. If you add these, they become a value of 500. This also answers the 2nd question ; 65x + 60x = 500.

Answer:
5,50,500,5000,50000
Step-by-step explanation:
The first term is given
a1 =5
The second term is when n=2
a2 = 10 * a1 = 10 * 5 = 50
The third term is when n=3
a3 = 10 * a2 = 10 * 50 = 500
The fourth term is when n=4
a4 = 10 * a3 = 10 * 500 = 5000
The fifth term is when n=5
a5 = 10 * a4 = 10 * 5000 = 50000
