If y is 2.5 when x is 5 and y varies directly with x find y when x is 10

Step-by-step explanation:

y=2.5 and x=5

Then if x=10 then y=5

To solve this, you find out how much x changed, and then do the same thing to y.

So in this case, x=5 and then x=10. so that means we multiplied by 2.

So because y=2.5 and you multiple that by 2 you get y=5

Hope this helps!

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

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
