Answer: There are 500 ninth grade students at Richbartville high school.
Step-by-step explanation:
Let be "x" the number of ninth grade students that are at Richbartville high school.
You know that the number of ninth grade students take algebra is 450 and this amount represents the 90% of the the ninth grade students at Richbartville high school.
Knowing this, you can set up the following proportion:
The final step is to solve for "x" in order to find its value. This is:
Therefore, there are 500 ninth grade students at Richbartville high school.
EDIT: The answer I posted for the question is wrong, and I will fix it because i got confused this is all my fault xD Here is the correct way to solve it.
Ok, so first we have to find 1/8, 3/10, and 2/5 of 200.
I will just fastfoward that, and we get 1/8=25, 3/10=60, and 2/5=80.
(To find these, you multiply 200 by each fraction).
Next, we will add all the numbers, and we will get 165.
Remember, there is still one more season left, so we subtract 165 from 200 to get
the remaining amount of people who voted for winter.

Answer: Herba has a greater balance and Nour has more debt.
Step-by-step explanation: Herba's account balance is a positive number and is clearly greater than Nour's account balance; therefore, Herba has a much greater balance. On the other hand, Nour's account balance is a negative number and is clearly less than Herba's; therefore, Hour is in more debt since he has to pay back the money that he borrowed.
Answer:
(top line) y=4/5x + 0, (bottom line) y=4/5-0.32
Step-by-step explanation:
so take the equation y=mx+b
b is the y intercept, which is where the line crosses (0,b)
the m is the slope, which is rise/run.
If the lines are parallel, the slopes are the same, just different y intercept
