Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.

She sells four loaves of bread.
Step-by-step explanation:
First, convert you fractions to decimals.
13 1/2 = 13.5
2 1/4 -2.25
Next, divide 13.5 by 2.25.
13.5/2.25=6
Two thirds of 6 is 4.
Therefore, the baker sold four loaves of bread.
Answer: 18% of youth used the internet elsewhere.
Step-by-step explanation:
At first, this problem might seem confusing since there could be places other than home with different percentages, and it feels as if you don't know enough to solve the problem.
But in reality, it breaks down to home or any other place in the world! If you're not at home, you need to exist somewhere.
So, it's actually as simple as 100% (you cannot have a total greater than 100% in the real world) - 82% = 18%
So, 18% of youth used internet in a place other than home.
