What is the value of x drawing not to scale

i just took the test, the correct answer is .. 31.5 in.

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

y=-2x+1500

step-by-step explanation:

+1500

2 over one
