A is the Wright way to go I think it I am high off coke
(n+1)x 2=10
2n+2=10
2n=8
n=4
As three hours divided by 2 is 1.5 hours, we know that to find how far the person walks in hours, we simply have to double the distance the person walked in 1.5 hours.
2.4*2=4.8
The person walked 4.8 miles in three hours.
Does that make sense?
1.7(a+3)
2.5(x-1)
3.prime
4.3(5p-9)
5.3(15k-4)
6.8(3p+1)
7.47-5-2m+8m=42+6m=6(7+m)
8.2*10a-2*7b-10b-2a
20a-14b-10b-2a
18a-24b=6(3a-4b)
