Your sister can get $30 per day for selling clothes at the market. but she has to $60 at first for renting a stand. you can get $20 per day for neighbor rake lawns. after how many days will your sister earn as much as you?

After 6 days

Step-by-step explanation:

Let x represent the number of days after which the my earning and my sister's earning will be same,

∵ sister gets $ 30 per day,

So, her revenue after x days = 30x,

Also, her expenses in renting = $ 60,

Thus her earning = revenue - expenses = 30x - 60

Now, my earning is $ 20 per day,

So, my earning after x days = 20x

⇒ 30x - 60 = 20x

30x - 20x = 60,

10x = 60

⇒ x = 6

Hence, after 6 days my earning and my sister's earning is same.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
