Find the distance from point a (7/8, -1/8) to point b (-1/8, 7/8)

 sqrt(2)    ≈1.414213562

Step-by-step explanation:

Distance is found by the formula

d =sqrt ( (x2-x1)^2 + (y2-y1)^2)

   = sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)

      sqrt( (-8/8)^2 + (7/8 +1/8)^2)

       sqrt( (-1)^2 + (1)^2)

        sqrt ( 1 +1)

         sqrt(2)

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
