Step-by-step explanation:
I think that is your answer because in the Himalayas it lies between latitudes 26.
(n+7)2
= (n)(2) + (7)(2)
=2n+14
Explanation:
Addition of fractions can be accomplished using the formula ...
a/b + c/d = (ad +bc)/(bd)
Usually, you are asked to find the common denominator and rewrite the fractions using that denominator. It is not necessary, but it can save a step in the reduction of the final result. Here, we'll use the formula, then reduce the result to lowest terms.

13. 5/6 +9/11 = (5·11 +6·9)/(6·11) = 109/66 = 1 43/66
___
14. 7/20 -5/8 = (7·8 -20·5)/(20·8) = -44/160 = -11/40
___
15. 1/5 -1/12 = (1·12 -5·1)/(5·12) = 7/60
___
Dividing fractions can be accomplished different ways. I was taught to multiply by the inverse of the divisor. ("Invert and multiply.") Here, that means the problem (2/7) / (1/13) can be rewritten as ...
(2/7) × (13/1) . . . . . where 13/1 is the inverse of 1/13.
You can also express the fractions over a common denominator. In that case, the quotient is the ratio of the numerators. Perhaps a little less obvious is that you can express the fractions using a common numerator. Then the quotient is the inverse of the ratio of the denominators: (2/7) / (2/26) = 26/7. (You can see how this works if you "invert and multiply" the fractions with common numerators. Those numerators cancel.)

I think maybe 3 miles? Because 6 divided by 2 (the two days) equals 3. So if he ran a hour on Sunday then he ran 3 miles
