Select all equations that have x = 3 as a solution.

Plug in a 3 every time you see an "x" and the left side should equal the right side

Step-by-step explanation:

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

b. b < 1 might be the correct answer
