Answer:
$100.00
Step-by-step explanation:
If we are rounding to the nearest 10, then we only have to look at 96. Since 6 is bigger than 5, we round up to 100.
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
Answer:
The numbers are 9, 19 and 76.
Step-by-step explanation:
Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.
The first number in terms of x:
![x - 10](https://tex.z-dn.net/?f=x%20-%2010)
The second number in terms of x:
![4x](https://tex.z-dn.net/?f=4x)
If we add them all up, these 3 numbers in terms of x must be equal to 104, so:
![x + (x - 10) + (4x) = 104 \\ x + x - 10 + 4x = 104 \\ 6x - 10 = 104 \\ 6x = 114 \\ x = 19](https://tex.z-dn.net/?f=x%20%2B%20%28x%20-%2010%29%20%2B%20%284x%29%20%3D%20104%20%5C%5C%20x%20%2B%20x%20-%2010%20%2B%204x%20%3D%20104%20%5C%5C%206x%20-%2010%20%3D%20104%20%5C%5C%206x%20%3D%20114%20%5C%5C%20x%20%3D%2019)
Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:
![19 - 10 = 9](https://tex.z-dn.net/?f=19%20-%2010%20%3D%209)
![4 \times 19 = 76](https://tex.z-dn.net/?f=4%20%5Ctimes%2019%20%3D%2076)
The first number is 9, second number 19 and the third number 76.
