The two longest rivers in the world are the Nile and the Amazon. Together, they are 8145 miles, with the Amazon being 145 miles shorter than the Nile. Find the length of each river.
Let x = the Amazon
x + x + 145 = 8145
2x = 8,000
x = 4,000
la=ln-145
la+ln=8145
ln-145+ln=8145
2*ln=8290
ln=...
Let's denote the length of the Nile as N.
Since the Amazon is 145 miles shorter than the Nile, we can represent the length of the Amazon as N - 145.
According to the given information, the total length when you add the Nile and the Amazon is 8145 miles:
N + (N - 145) = 8145
Now, we can solve this equation to find the length of each river.
Combining like terms, we have:
2N - 145 = 8145
To isolate the variable N, we can add 145 to both sides of the equation:
2N - 145 + 145 = 8145 + 145
2N = 8290
Next, we can divide both sides of the equation by 2 to solve for N:
(2N)/2 = 8290/2
N = 4145
Therefore, the length of the Nile (N) is 4145 miles.
And the length of the Amazon (N - 145) is 4145 - 145 = 4000 miles.
So, the Nile is 4145 miles long and the Amazon is 4000 miles long.
