Step-by-step explanation:
Lets say Y is the amount they will save.
So Melinda's savings could be described by the equation Y=22+10X, where X is the number of weeks. The same goes to George, but his equation would be Y=10+13X.
To save the same amount, their equations must match:
22+10X = 10+13X
Solving this, one gets
12 = 3x
=> 4=x
So the answer is 4 weeks.

Answer:
18 feet long.
Step-by-step explanation:
Let the bottom section be x feet long, then:
x/6 + x/2 + x = 180
Multiply through by 6:
x + 3x + 6x = 1080
10x = 1080
x = 108 feet,
So the top section = 108/6
= 18 feet long.
