Answer:
160:340
Step-by-step explanation:
The hours between 2:00pm and 4:00pm is 2 hours. If originally 350 freshman and 200 sophomores are at the carnival, and 20 freshman leave every hour, we can determine how many freshman left in 2 hours:

and if 35 sophomores arrive every half our, we know that for every two hours there is 4 half hours, therefore:

The amount of freshman at 4:00pm:

and the amount of sophomores:

the ratio is 160:340
Answer:
12,500-11,625=875
875/12,500=7/100
7/100*100=7
The percentage reduction is 7%

Answer:
x = 750
Explanation:
25x = 30
1. Multiply 25 by 30
25 * 30 = 750
2. Divide 750 by 25
750/25 = 30
3. Divide 750 by 30
750/30 = 25
Therefore, x = 750
Answer:
x=2.
Step-by-step explanation:
It is given that points A, B, and C are collinear. Point B is between A and C.
Using segment addition property, we get

It is given that AC = 3x + 3, BC = 3, and AB = 2x + 2.


Isolate variable terms.


Therefore, the value of x is 2.
