Six more than eight times a number is 21

If your question is about creating an equation, the answer is

8x + 6 = 21                   6 more is after 8x

If your question is about the value of the equation, the answer is

1.875 or 15/8

Step-by-step explanation:

8x + 6 = 21                       Subtract 6 on both sides

      8x = 15                      Divide 8 on both sides

         x = 1.875

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
