Answer:
225
Step-by-step explanation:
If you divide 675 you'll get 225. 225 times 4 will be 900. But 225 times 3 will be 674. So each 1/4 will be 225.
Answer:
x = 4
Step-by-step explanation:
We know that M is the mid-point of AB. So,
AM = BM ( A mid point divides a line segment into 2 equal parts. )
Also it's given that length of AM is 20 & length of BM is 3x + 8.
But as AM = BM ,
![20 = 3x + 8](https://tex.z-dn.net/?f=20%20%3D%203x%20%2B%208)
![= > 3x = 20 - 8 = 12](https://tex.z-dn.net/?f=%20%3D%20%20%3E%203x%20%3D%2020%20-%208%20%3D%2012)
![= > x = \frac{12}{3} = 4](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20x%20%3D%20%20%5Cfrac%7B12%7D%7B3%7D%20%20%3D%204)
Answer:
im finding the answer now but what do you want me to find
Step-by-step explanation:
The temperature at 10 pm is -3 degrees
Given:
Your distance y (in meters) from the finish line x seconds after you begin your leg of a relay race is
![y+4x=100](https://tex.z-dn.net/?f=y%2B4x%3D100)
Opponent's distance is
![y+3.7x+94](https://tex.z-dn.net/?f=y%2B3.7x%2B94)
To find:
The distance you need to run to catch up with your opponent.
Solution:
We have,
...(i)
...(ii)
Subtract (ii) from (i), we get
![y+4x-y-3.7x=100-94](https://tex.z-dn.net/?f=y%2B4x-y-3.7x%3D100-94)
![0.3x=6](https://tex.z-dn.net/?f=0.3x%3D6)
Divide both sides by 0.3.
![x=\dfrac{6}{0.3}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B6%7D%7B0.3%7D)
![x=20](https://tex.z-dn.net/?f=x%3D20)
Put x=20 in (i).
![y+4(20)=100](https://tex.z-dn.net/?f=y%2B4%2820%29%3D100)
![y+80=100](https://tex.z-dn.net/?f=y%2B80%3D100)
![y=100-80](https://tex.z-dn.net/?f=y%3D100-80)
![y=20](https://tex.z-dn.net/?f=y%3D20)
They will meet at (20,20). It means at 20 meters from the finish line after 20 seconds from the beginning.
Put x=0 in (i), we get
![y+4(0)=100](https://tex.z-dn.net/?f=y%2B4%280%29%3D100)
![y=100](https://tex.z-dn.net/?f=y%3D100)
It means, initially the total distance you and finish line is 100 meters.
You will catch your opponent 20 meter from the finish line. So,
![100-20=80](https://tex.z-dn.net/?f=100-20%3D80)
Therefore, you need to run 80 meters to catch up with your opponent.
