Answer:
The error is: The solution shows the Sam's age and the problem asked for Micaela's age.
Solution fixed: 
Micaela is 17 years old now.
Step-by-step explanation:
The error is: The solution shows the Sam's age and the problem asked for Micaela's age.
To fix the error, you can set up these equations based on the information given:
Solve for "s" from the first equation:
Substitute this equation into the second equation:
Now you need to solve for "m":
Micaela is 17 years old now.

Answer:
5000 Australian Dollars
Step-by-step explanation:
To find out how many Australian dollars need to be sold, we first need to find the profit of a single dollar sold.
We will be using the formula for profit, which is:
Profit = Total Revenue - Total Cost
Now we define the available variables.
Total Revenue = 81.40
Total Cost = 80.20
Profit = 81.40 - 80.20
Profit = rs 1.20/dollar
Now we have to find how many dollars we have to sell to get a profit of rs 6000.
We simply divide the amount of profit that we want to the price per dollar.
Total Profit = 6000
Profit per dollar = 1.20
This give us:
6000 / 1.20 = 5000 Australian Dollars.
Alright, so since I don't have an example question, I will make one up.
there are 8 coins in total. there are 6 dimes. What is the fraction of dimes to coins.
you would put the amount of dimes on the top and the total on the bottom.
Answer: 6/8 which can be simplified to 3/4
Or another Example:
There are 12 pieces in the pizza. Billy took 4. what is the fraction of the slices left.
it would be 4-12= 8
Answer: 8/12 which can be simplified to 4/6 and then to 2/3
Hope that helped.
Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
