The length is 10 because this is a right triangle and based on the pythagorean theorem, the sum of the squares of the legs equals the square of the longest side.
6 squared plus 8 squared is 100, which is 10 squared.
The answer is 10.
2/3 = 8/12
reason:
2/3 * 4/4
-85 -35-(-47) when you find the difference your subtracting causing a negative to subtract negatives going up the number line more negatives increase
Is the question how much it cost per kg?
If so, divide $13 by 1 3/7 kg.
13/(1 3/7) = 13/(10/7) = 13 * 7/10 = 91/10 = 9 1/10
Answer is 9 1/10 dollars per kg.
(Assuming I guessed your question correctly.)
