Answer:
32
Step-by-step explanation:
The total length of the two bridges is 5020 ft.
In order to find the combined length of these two bridges, simply add the two numbers together.
4260 + 760 = 5020.
A 
B denotes to all common elements in both A and B
- Sample space=S={1,2,3,4,5,6,7,8,9,10}
So
2 is common
Hence
A $\cap$ B={2}
Let the two numbers be x and y, with y being larger than x.
Then y=3x+1.
Also, 8x-2y= 10.
The first equation has already been solved for y. Substitute 3x+1 for y in the second equation:
8x-2(3x+1)=10, or 8x - 6x - 2 = 10, or 2x = 12 and x = 6.
If x = 6, then by the first equation y must be 3(6)+1, or 19.
The numbers are 6 and 19.
