Answer:
X = 5
Step-by-step explanation:
28 = 7x + 3 - 2x
28 = 5x + 3
28 - 3 = 5x + 3 - 3
25 = 5x
25/5 = 5x/5
X = 5
I do believe that those are called numbers

Answer:
10 miles
Step-by-step explanation:
Given: Bike goes 8 miles south and then 6 miles east
To find: distance between the final point and the starting point
Solution:
<u>Pythagoras Theorem</u>
In a right angled triangle, square of hypotenuse is equal to the sum of squares of the two sides.
In ΔOAB,
![OB^2=OA^2+AB^2](https://tex.z-dn.net/?f=OB%5E2%3DOA%5E2%2BAB%5E2)
Put ![OA=8\,,\,AB=6](https://tex.z-dn.net/?f=OA%3D8%5C%2C%2C%5C%2CAB%3D6)
![OB^2=8^2+6^2=64+36=100](https://tex.z-dn.net/?f=OB%5E2%3D8%5E2%2B6%5E2%3D64%2B36%3D100)
Take square root on both sides.
![OB=\sqrt{100}=10\,\,miles](https://tex.z-dn.net/?f=OB%3D%5Csqrt%7B100%7D%3D10%5C%2C%5C%2Cmiles)
So, distance between the final point and the starting point is 10 miles
